Favorite tool I’ve ever purchased
Bought this several years ago, and it’s still working. This is my absolute favorite tool I own. All of the different pieces make it extremely useful. It has decent power for what it is, but not as strong as an impact driver. Two things I don’t care for: the drill accessory doesn’t stay in the magnetic chuck very well, and the lanyard sometimes makes contact with the switch when you put the screwdriver in the storage case. It was cheap, and very very useful for anything around the house.

Very useful. Lots of cool features.
This screwdriver kit was just what I wanted. I needed something that I could use for household tasks and have it all in one nice single package. The little case for this tool keeps it neat and tidy and I don't fear losing bits and pieces. There are lots of features included. My rotary tool set could do for some of the uses I anticipated, but the rotary tool is corded, and I wanted something that was cord-free. Also, I wanted something fairly lightweight that was just straight like a manual screwdriver and not a gun like a drill. Most of the time I need a power screwdriver just to screw things straight in. I also wanted something that would not be too large to fit into tight corners. Something that I hadn't thought of was that it would be nice to be able to drill pilot holes without having to get out my drill. Check! They thought of it and is very convenient. Since I have it, I had a little rack I wanted under the sink space, and I was able to build it in only about 15 minutes. Another feature is that there is a socket wrench set that in just the couple of days that I have had it has come in handy. Never really thought I would use that! The sockets go from 6 mm to 13mm (metric only) but much to my surprise every time I needed a socket, I needed a metric rather than Imperial measure. There is a good assortment of screwdriver bits, including some esoteric star bits. I have many additional screwdriver bits with my rotary tool set, and the shafts are the same size, so if there is something missing, I am sure I will be able to find the right size bit without having a trip to the hardware store. I cannot address how good the battery life is compared to other electric screwdrivers, but I haven't felt I needed more. The included cable, which goes from a large USB A to a smaller trapezoidal USB B, plugs easily into a power hub I keep on my desktop, and it seems to be back to full power in an hour and a half or less. One final note just to help someone out who thinks that a part was left out. When I opened the package, I looked and looked, but could not find the Hex Flex Shaft, I even went so far as to call for product support. However, while the man was looking to see if he could get a replacement sent out, I started viewing the videos, and saw a man lift out the bottom of the box, and Voila! There it was. So, one potential problem fixed instantaneously. That flexible extension was one of the selling points of the tool since it lets you get into tight spaces more easily! All in all, I am very pleased with the set and highly recommend it. I am thinking about purchasing it for a friend who recently lost her husband, since she has fairly decent skills with manual tools but is afraid of power tools. This seems ideal to get her past that fear.

Easy to use, carefully read manual
This screwdriver is very solid and easy to use. However, I had to re-read parts of the manual to verify some things such as the ways you would turn it on and change modes. This worked great for most of the applications I had for a screwdriver, and the LED on the end made it so much easier to use on PC assembly. However, trying this on furniture assembly or anything where you would need a lot of force wasn't great. For furniture and large force applications the screwdriver would seize up, even at max speed/force setting. After that I had to switch to another screwdriver to finish the job. The kit comes with all the heads you would need for basic use though, and the charger is great. Overall, great item but could use some tweaking for anything beyond very basic use.

Love the long charge best coffee now
My coffee always tastes great now no more expensive lattes for me. So easy to use and stands up next to my coffee maker. Love that it is cordless and rechargeable. The charge holds a long time like two weeks and I use it daily.

the best electric screwdriver on Amazon
I've bought many different electric screwdrivers on Amazon and this is so far my favorite, it comes with all kinds of extra bits and accessories, and a really really nice carrying case, excellent battery life and I love the RPM knob! plenty of torque too and, best of all, the lights stay on for a bit when not pressing the button! update: my screwdriver tip came out of the socket one day when a bit wouldn't come out, i messaged the manufacturer and they sent me a totally free one, such a fantastic company!

Perfect for computer builders or putting Ikea Furniture together!
Built 2 computers with it so far. And assembled a desk. There is no doubt this is perfect for predrilled holes into actual wood. Now imagine that with Fiber board furniture, It'll be a breeze for this to drill or screw into. There are many bits included which uses the common sizes for furniture and an extension bit, Also includes a flexible shaft. Speed/power is adjustable with a single slider at the back. Keep in mind this is an electric screwdriver. Not a power-drill. I had a Xiaomi Wowstick F1 which broke with about 24 hours of total use time(Had it for 7 months). Obviously this thing overpowers it but is not for precision uses. Hoping it lasts longer. I would buy some longer bits or an extension and put it under the tray where it holds all the included bits. Under the tray is also where the flexible bit is. Got lots of space to add in your own bits. The good: -Much power! Can screw in self tapping screws into computer case fans on the 3rd setting no issues! -Adjustable power and speed, Setting 1 or 1 1/2. Will screw computer parts together fast and safely without over tightening - Long power life. -Inclusion of many bits and some drills. -Uses standard 1/4 bits. -Small details like oil filmed bits. Glad they account for rust. some small downsides: -The 3 LED's are not bright at all. has 3 led's which doesn't really do much of anything. Will definitely help in very dark situations. -Included bits are very very low quality. But for 30 bucks and this much power. And the amount of bits you get. It's passible, Also not magnetic and very short. Recommend getting longer bits! -Micro usb, By now it's better to get these tools with a USB C. It would charge faster and be more safe. -No charging while using the screwdriver, I would like to use the screwdriver while its charging! No man should be stranded with a non working drill. -No manual turning(nor clutch) When the drill is dead or isn't giving actual enough power you can not turn whatever you're doing manually. -No locking chuck. Magnet seems to do a fine job keeping bits in. Will keep updated if I have any issues.

Love love love this little rechargeable screwdriver/drill
I'm a crafter, and recently have gotten my feet wet with resin. Many pieces needed a hole drilled to insert eye hooks, wires, lollipop sticks, etc. and the big drill was just too cumbersome. This works perfectly for all these applications. It's light weight which makes it easy to hold steady, it's versatile (I can even insert a paddle with a hex base to mix my resin), and very easy to use. Wish I had found this years ago. BUT it's modern with its usb charger so probably was not available years ago. As a 50+ year crafter, I wholly recommend this if you need a drill or screwdriver for small items. And yes it does work on resin.

broke quickly
Used to work well, but after 2 months of use, the screwdriver will never turn off. The directions say it will automatically turn off after 10 minutes, but instead the screwdriver randomly turns on and won’t turn off hours after I’ve finished using it. Several times I have put the screwdriver away after using it, and hours later I hear the loud noises of the screwdriver turning on by itself without anything touching the buttons. Since it never turns off and it randomly changes direction while you’re using it, it is now useless.
