EARLY IMPRESSIONS: Coming from having owned the best of the best mice and trackballs from Logitech such as my current Marble Trackball, the M570 (which possibly contributed me the De Quervane syndrome I have now) and the Anywhere Mouse, not to mention scores of other mice and trackballs over the years include the 1990s version of the Kengington Expert Mouse -- I was, at most, expecting to marginally impressed by the Kensington Slimblade Trackball. But it took me only 15 minutes of acclimating and fine tuning the settings that I realized that this is a vast step up from my Marble Mouse. I'll have more to see in an updated review, but for now, here's few quick impression 5 star ratings, 5 being best: ***** Buttons: Excellent feel and "just right." In fact, were it not for the fact that some people mentioned the issue of having to press the buttons harder than they would expected, I never would have given this issue a second thought. The click pressure is about what I'd expect and has been a non-issue for me. I suspect that some people have this problem because the are pressing the keys to close to the hinge. But where my thumb and fingers naturally tend to fall are the areas that are farthest distance from hinges. ***** Scrolling: One of the best innovations since Xerox PARC invented the mouse. Honestly, even after all the glowing reviews in desertcart, I wasn't expecting it to be this natural, not to menion -- fun. Try it and you may never want to go back to a scroll wheel. ***** Ease of use and precision. Pointing and click is what you'd expect from a $99 trackball. Using a bigger ball than is the case on my Logitech Marble Mouse, does improve precision. This is especially the case because I am right handed, but need to use my left hand for this trackball. Many times when using my previous trackball, the Logitech Marble, I'd aim to put the mouse arrow on top of a small screen object (such as a line on my DropMind Mindmap) and found it difficult. So far, I'm finding myself about perform the same surgical actions more easily with the Kensington. ***** Smoothness of the ball. Initially, I found that would you do a rapid twist when scrolling, there's some kind of weird slight scraping vibration. The sound went away after a few days after natural oils from my fingers lubed the ball sufficiently. ***** TrackBallWorks Software. Works find and allows me to control all the buttons and chordings. So I was able to switch the traditional mouse click buttons to left-handed mode, use the top buttons for back and forward with browsing the Internet, refresh with bottom chord, and launch volume controls with upper chord. This is way more than what I could do with my Logitech Marble Mouse. **** Construction. ON THE PLUS SIDE, it's a beautiful, gleaming piece of modern art on my desk. ON THE NEGATIVE SIDE: The should have engineered the click buttons so that needed pressure to click is the same no matter were you click. While click-pressure has not been a problem for me in general, there are occasions where I click different areas of the button and it's unexpectedly harder than my finger expects. AS FOR THE BALL: My ball has dropped onto my hardwood floor about six times since I got this thing. Each time, I'm wondering if I dented or scratched it. I really wish they had fingered out a way to hold it in there. Conclusion: The days and weeks will tell. But for now, this is a candidate for being the best mouse/trackball input device I've ever used. UPDATE 9/18/2013 Well, I've come to the conclusion that this is the best mouse/trackball input device I've ever used. It beats all trackballs I've ever used. PLUS, it beats all mice I've ever used. That's a major shift because until this point, I've never had a trackball that has been as accurate, precise and easy to use as a good mouse. This Kensington Slimblade finally does it. It totally trounces Logitech and I've deleted all Logitech drivers from my main computer. I am amazed that it's not at or near the top of the charts. Well, for sure, in opinion, it deserves to be there. UPDATE 10/16/2013 Still going strong. No complaints. The one unfortunate thing is that many people might be scared off by the early reviews which reported problems with the the TrackBallWorks driver. That problem has long been fixed and it's been smooth sailing for me and many other users. If you're looking for the greatest trackball in the world and an alternative to the Logitech Marble Trackball (which I also own), this is worth a try. Review: Excellent ball - The ball is excellent. Moves smoothly, so does the cursor. It is great that it is so easy to remove. Kensington software does not recognise this mouse if it is plugged in to a monitor, connected to a KVM and then to a PC. The mouse is still usable in this case, but with a standard Microsoft mouse driver - without customisation. Microsoft driver allows to tweak cursor speed, click lock etc. Once the mouse is plugged in to a PC, then Kensington software recognises this mouse and full customisation becomes possible. The software is good. I needed to check Youtube for details of how to re-assign buttons. The buttons are usable. Scrolling by twisting mouse ball is convenient. Here is an idea for another version of this mouse: why not add a separate item, connected to this mouse with a (USB?) cable, which can be placed apart and used by the other hand? The main mouse - shaped similarly to this product - would house only a ball. The current design is spot on. The other item would house buttons: - left, right buttons - scroll wheel - a button to fix horizontal / vertical axis of ball movement - other customisable buttons - a trackpad - for a quick jump to any part of the screen Ideally these 2 items would be available for purchase both together and separately - in case one of them becomes faulty and needs to be replaced. ## Features - Low-profile shape and silver metallic finish deliver ergonomic comfort and beautiful aesthetics - Requires less arm and wrist movement (for better comfort) and takes up less desk space than a traditional mouse - Laser tracking delivers precision cursor control - Ambidextrous design - Free downloadable KensingtonWorks software provides button customization ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001MTE32Y | | Additional Features | Movement detection technology:Trackball | | Antenna Location | Office | | Are Batteries Included | No | | Are Batteries Required | No | | Best Sellers Rank | #1,020 in Computer Mice | | Brand | Kensington | | Button Quantity | 4 | | Color | Black | | Compatible Devices | Windows 7, Windows 8, Windows 8.1, macOS 10.8, Windows 10, macOS X 10.11, macOS 10.10 or above, Chrome OS 44 or above, macOS 10.9, macOS Sierra 10.12 | | Connectivity Technology | Wired | | Customer Reviews | 4.3 out of 5 stars 2,064 Reviews | | Enclosure Material | Silver | | Global Trade Identification Number | 00085896723271, 05050914713317 | | Hand Orientation | Ambidextrous | | Hardware Platform | PC | | Item Dimensions L x W | 6"L x 5"W | | Item Weight | 11.2 ounces | | Manufacturer | Kensington | | Mfr Part Number | K72327US | | Model Name | SlimBladeβ„’ K72327EU Trackball | | Model Number | K72327EU | | Movement Detection | Trackball | | Movement Detection Technology | Trackball | | Number of Batteries | 1 AAA batteries required. | | Number of Buttons | 4 | | Operating System | Windows 8 | | Range | 6.0 feet | | Special Feature | Movement detection technology:Trackball | | Style Name | Mouse | | UPC | 809385660935 097009492066 100177260228 085896645887 763615904803 638458744988 640206607070 807030490470 031112194004 872182664895 800187705022 803982758279 029521830347 031112582351 662919001648 823019652431 804993501564 666667458037 809098923051 012304048473 102930735899 095009492062 085896723271 096009492069 724627170587 641438718763 809185809343 858967232718 640026224976 074437854154 8067920398… | | Warranty Description | 2 year warranty (Only valid if purchased through Kensington Authorized Resellers) | ## Product Details - **Brand:** Kensington - **Color:** Black - **Connectivity Technology:** Wired - **Movement Detection Technology:** Trackball - **Special Feature:** Movement detection technology:Trackball ## Images ![Kensington Wired SlimBlade Trackball Mouse (K72327U), Black - Image 1](https://m.media-amazon.com/images/I/61h4ypeduDL.jpg) ![Kensington Wired SlimBlade Trackball Mouse (K72327U), Black - Image 2](https://m.media-amazon.com/images/I/51U6V2cwVhL.jpg) ![Kensington Wired SlimBlade Trackball Mouse (K72327U), Black - Image 3](https://m.media-amazon.com/images/I/518jXIcRQUL.jpg) ![Kensington Wired SlimBlade Trackball Mouse (K72327U), Black - Image 4](https://m.media-amazon.com/images/I/51CvsVsIjlL.jpg) ![Kensington Wired SlimBlade Trackball Mouse (K72327U), Black - Image 5](https://m.media-amazon.com/images/I/31v1asHl0IL.jpg) ## Available Options This product comes in different **Unit Count, Style** options. ## Questions & Answers **Q: Which is the difference between Expert trackball and Slimblade Trackball? Which one is better? I know that Slimblade doesn't have Removable Wrist Rest** A: The slim blade is a lower profile trackball. Theoretically it doesn't need a wrist rest because it sits closer to the desk. Also there is no scroll ring. Instead you twist the track ball like a doorknob to scroll. I have had both trackballs and prefer the expert over the slim blade. I had significant wrist pain from using the slim blade everyday. The pain became significant after about a month of using it. I never had that problem with the expert with wrist rest. I have since returned to that style trackball. After a few days the wrist pain started to subside. After 2 weeks it was gone. I think the main culprit was the buttons. They are very stiff and require significant effort to depress them. Doing a lot of Photoshop retouching where have to hold down the button while manipulating the ball is what cause the strain injury. Stick with the expert. It's more comfortable to use and I like the scroll ring better than twisting the ball. **Q: Anybody else getting a screeching sound when doing twist for scrolling? Like a kid trying to play a clarinet. If "Yes" does it ever go away?** A: Screeching started about 8 months in for me. I tried cleaning, lubricating it, and still get the screeching when I twist the trackball to scroll. It's loud enough that other people in the office ask what that sound is, and it's annoying enough to make me embarrassed to even use the device. Been using it for 9 months now, so far, no it doesn't go away. Kensington support's first recommendation was to "blow some compressed air around the scroll wheel." Considering there isn't even a scroll wheel on this device, it's rather hard to follow their recommendations for fixing the screech. Switching back to a mouse until I get a better response from Kensington support. For a ~$100 trackball, I hope they have a better answer than to clean parts of the device that don't exist. Will update this answer if there's anything worth adding. **Q: Which is the difference between Expert trackball and Slimblade Trackball? Which one is better? I know that Slimblade doesn't have Removable Wrist Rest** A: The Slimblade takes a bit of "training". I use 2 fingers, one to spin the ball, while the other sits on top of the ball to keep it spinning about its axis. Expert Advantage: single finger scrolling and no muscle training Slimblade Advantage: MUCH more scrolling with a single gesture when I give it a hard spin; smoother action for fine control **Q: Does this model fit an 8 ball?** A: In the original Kensington trackballs you could swap out the ball for an eight ball (I had one so equipped) but you can't with their newer models. The size of the ball is different, and as another answer pointed out, these use optical tracking where the originals used mechanical tracking. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Makes you look forward to Mondays *by P***C on September 13, 2013* Quick and easy setup.

Moves smoothly, so does the cursor. It is great that it is so easy to remove. Kensington software does not recognise this mouse if it is plugged in to a monitor, connected to a KVM and then to a PC.

I'm pleased to say my reluctance was ill-founded: There's a lot to like about the Kensington SlimBlade. First, it feels like it has a *much* better build quality than the piece-o'-junk M570 that it replaced. Some might be annoyed by the buttons as they do need a firm push, but I prefer this to overly sensitive buttons that provide no tactile feedback. The base of this device has a good weight, so it doesn't slide around on the table. The trackball itself glides smoothly, and I like the fact that it can be easily removed from the base for cleaning. The base has a low profile, so it fits in my hand comfortably. I was skeptical regarding the 'twist' scrolling feature, but I'm pleasantly surprised by how easy it is (imagine turning a doorknob). I have found the scrolling can be a little 'herky-jerky' sometimes and that the scroll speed is not consistent across applications, but overall it does fine. For applications I use frequently I create a unique profile via the TrackballWorks configuration panel to fine-tune the scrolling, and for those I use infrequently I just live with it. I've also noticed that in games with small click spots the twist scrolling can be a challenge since even a little nudge on the x or y axis will move the pointer out of the click spot, but I'm not so much the gamer that this is an issue for me. I also thought highlighting text for dragging would be more work with this device, but I've programmed the upper-right button to initiate a drag, so there's no need to hold a button down while moving the trackball to highlight text. I've quickly grown to love this feature. I agree with others that the configuration software could be more flexible and offer more options, but I have found it sufficient for my day-to-day use and have had no trouble with it. I do like the fact that you can define operations triggered by pushing the top two or the bottom two buttons simultaneously, and I have utilized this feature in several applications. I also agree that this device is a little pricey, but have no objection to paying extra for quality and value. If the SlimBlade gives me no trouble and is still operational years from now then it's money well spent in my book. Though at this point I'd still prefer a high quality wireless thumb trackball with a scroll wheel, I do like the Kensington SlimBlade Trackball more than I was anticipating. I'd recommend it to anyone who prefers a trackball over a traditional mouse. ## Frequently Bought Together - Kensington Wired SlimBlade Trackball Mouse (K72327U), Black - Kensington ErgoSoft Wrist Rest for Slim Mouse/Trackpad, Black (K52803WW) - LZYDD 55mm Huge Trackball Replacement for Kensington Wired SlimBlade Trackball Mouse/Kensington Expert Wireless Trackball Mouse (K72359WW) /K64325 /k72327 (Black) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/437245-kensington-wired-slimblade-trackball-mouse-k72327u-black](https://www.desertcart.sn/products/437245-kensington-wired-slimblade-trackball-mouse-k72327u-black) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-03*
