Kensington Orbit Trackball Mouse, Wired Ergonomic Trackball, 40mm Ball

Love this mouse a lot better than others on the market, it a quick reaction mouse gamers could easily use this mouse

I have used Kensington trackballs for years (this optical one will be my 5th), they occupy less space than a mousepad, the mouse cable does not get pulled about and they do everything a standard two-button mouse could do, only better. The older mechanical units are fine when you first get them but as time goes by the small rubber wheels get clogged with dust and fluff, which can be cleaned off as first but in time the rubber of the wheels turns to black goo and then the whole mechanism will stop working. If the rubber wheels could have been replaced, then perhaps I would never have bought the optical unit? I expect this trackball never to wear out and therefore be my last. This optical trackball is really very much lighter to use than the mechanical ones but the mass of the ball seems about the same and I can go whizzing from one side of the screen to the other, letting the trackball do all the work. It is equally useable with the left hand as well as the right and always being in the same position on the desktop, it makes for a strainfree existence. Worth the money? Absolutely, I would recommend this device anytime. If it was wireless it would be even better.

I picked up the Kensington Orbit Wired Trackball to help with some wrist strain, and overall, it’s a really solid, comfortable device. The ambidextrous design is great, and it feels high-quality on my desk. Here is my honest breakdown after spending some time with it: The Tracking: Out of the box, this thing is *fast*. The tracking sensitivity was so high that the cursor was flying across my screen at the slightest touch. I had to go into my system settings and significantly reduce the pointer speed to get it under control. Once adjusted, it works perfectly and is incredibly precise, but be prepared to tweak your settings on day one. The Ergonomics: As someone looking for an ergonomic alternative to a standard mouse, this delivers. It keeps your hand stationary and reduces wrist movement, which is exactly what I wanted. The Downside (No Scroll): The biggest adjustment for me—and the reason it loses a star—is the complete lack of a scrolling mechanism. I am so used to a traditional scroll wheel, and having absolutely nothing on this trackball to scroll through long webpages or documents is a bummer. You have to rely on clicking and dragging scroll bars or using keyboard shortcuts. Final Verdict: It gets **4 stars** from me. It’s a well-built, comfortable trackball that functions exactly as it should once you turn down the sensitivity. If you don't mind navigating without a scroll wheel, it's a fantastic buy!

I first started using a trackball mouse at work because I was getting a constant ache in my shoulder, which I put down to the movements using a regular mouse (my job involved me being on the computer most of the day). Once I'd been using the trackball for a week or so, I noticed that the ache was easing up, and it soon disappeared. People at work struggle to use my mouse if they come over to my desk to show me something, but I took to it from day 1. I find if I try to use a regular mouse now I struggle until I get used to it. Great gadget, and very useful if you have limited room as it doesn't need to move - the ball on the top does all the work. I have 1 for both my home computer and laptop (can't get on with the laptops built in mouse at all). Kensington also do a trackball mouse that isn't optical, but it's worth paying that little bit extra for the optical. The other type picks up more dirt and fluff, which sticks to the rubber rollers that the ball sits on, the movement of which controls the curser. You have to keep cleaning the rubbers, and eventually they wear so the ball can't get any traction. The optical mouse still picks up fluff on the 3 little balls that hold the trackball, which also causes it to lose traction, but you just wipe off the fluff with finger or tissue and you're off again.

I've bought three of these, as they are (to me) the only ergonomic finger mouse that you can buy in the UK, bar the extremely overpriced Kensington slimblade which tbh isnt quite as good and isnt quite as ergonomic. As Amazon muddles all of these reviews together, this one is for the Kensington Orbit WITHOUT the scroll ring. I have.... A lot of issues with these and tbh this is a rant that could go on and on, but I still buy them as there's little real alternative if you want a genuinely ergonomic finger trackball. The bad: Base is naturally unstable - you will have to glue or stick something under the cable end or it will rock like crazy every time you use it without your hand on the rest. The buttons will give out after a couple of years of use. It uses that rubberised coating on the rest that inevitably goes skanky and sticky after a few years (and even quicker with regular use). The ball is... Sometimes manufactured ok and sometimes not. If the randomly generated pattern of the grey ball has a completely black spot on it (two of mine do) you will have a dead zone in the movement. Thankfully the ball is easily removable and can also be replaced with the blue ball from the orbit with scroll wheel which has a proper micro pattern and thus always works. The orbit with scroll is a truly dreadful mouse from an ergonomic perspective tho. The sensor is cheap as chips and is comparable to a very cheap office mouse. It would have been considered high end in 1999. Even worse is that it uses an energy saving mode (why???) so expect a second wake up lag every time you leave it alone for a minute. There is no ability to scroll. Personally this doesn't bother me much as I only use office programs (I work in law) I remember computers before scrolling was a thing and I'm handy with keyboard shortcuts, but there are programs out there outside of my profession that now require a scroll wheel of some sort. I get that this is a decades old design, but surely Kensington could find a way to implement a modifier button at least. The manufacturing is shoddy and very hit and miss. Black spots on the balls aside, I've had some very scratchy balls and the feel of the buttons on all of these is very inconsistent despite being the same model. The good: and the reason this review has three stars - there is nothing else currently manufactured and for sale in the UK that fits this ergonomic profile.

I've used two Kensington Orbital Optical Trackball (large grey ball) devices now, each one for over 5 years, and I have enjoyed using both! The size of the base is just right for my hands, the ball is nice and big, and easy to roll, and the two 'click' buttons are in the right position for use. I would personally recommend this mouse to anyone who just wants a comfortable, accurate, easy-to-use mouse, that takes up limited space on one's desk and hardly needs cleaning! My only wish is that somehow, the ball could be 'fixed' to the base so it doesn't fall out... that said, mine has dropped a few times when I've moved the mouse's location... so far, the ball has been none the worse for the experience and the mouse has continued to work with precision!

The ball floats in its lodging and is not held in place. The hand is quite raised and the absence of a scrolling functionality make it all frustrating. Plus it's loud and wobbly I returned it and am happy with the kensington orbit trackball with scroll ring instead. Works for either hand

Fits the hand well. Easy to set up. I have been using a well known marble mouse for years, but it appears to be obsolete now. Any on the secondary market are horrendously overpriced, so finding this as a replacement is great.

Le trackball Kensington Orbit Optical est un très bon trackball d'entrée de gamme, il peut se révéler un excellent choix pour qui veut découvrir à moindre coût le monde des trackballs, et le plaisir d'utiliser pareil périphérique. Les principales critiques que l'on entend au sujet des trackballs sont leur manque d'ergonomie, dépendamment que la boule soit centrale (pour une utilisation ambidextre), ou déportée (généralement dédiés aux droitiers) et l'absence de roulette. L'ergonomie est un facteur à prendre bien entendu en considération, mais celle-ci par définition est liée à la morphologie et aux attentes parfois très spécifiques de chacun, certains trouveront toujours ce trackball trop grand, d'autres trop petit, certains trouveront la boule trop petite, voire mal positionnée. Personnellement je trouve la taille de ce trackball plutôt modeste, il ne conviendra pas aux (très) grandes mains. Pour être objectif, je l'ai comparé au Kensington Slimblade, ainsi qu'au Logitech Trackman Marble... il est sensiblement plus petit que ces derniers. L'ergonomie étant quelque chose de très subjectif, ce sera à chacun de juger, mais après plusieurs heures d'utilisation intensive, je dois admettre que le profil choisi par Kensington n'est pas désagréable, il ne provoque aucune sensation désagréable ni de gêne particulière. Mais où est donc la roulette ? Je ne compte plus les remarques à ce sujet, certains n'hésitant pas à établir un lien direct entre l'absence de roulette et la possibilité d'effectuer un défilement (scrolling). Si il est vrai que la roulette est un confort indéniable pour effectuer un défilement, il ne faut pas perdre de vue qu'un trackball, par définition, permet d'effectuer nativement cette action, et ce au contraire d'une souris classique (sans roulette). En effet, avec un trackball, le défilement (scrolling) peut s'opérer très simplement en pointant la barre de défilement avec le clic gauche et, tout en maintenant le clic gauche enfoncé, vous utilisez la boule comme une énorme roulette... c'est silencieux, précis, bref... un vrai plaisir ! Vous pouvez même vous écarter de la barre de défilement tout en effectuant un "scrolling", attention toutefois de ne pas trop s'en écarter car au-delà de quelques centimètres la fonction de défilement s'interrompt. Il est important de préciser que Kensington propose, tout comme Logitech, un logiciel de contrôle pour ses périphériques, permettant, entre autres, de (re)programmer les boutons voire pour ce qui nous occupe, affecter une fonction particulière au clic simultané (clic gauche + clic droit). Il est donc très aisé d'affecter la fonction "clic du milieu" au clic simultané et de bénéficier dès lors d'un "scrolling" logiciel. Pour les personnes intéressées, vous devez télécharger le logiciel TrackballWorks 1.1.18 for Windows (32-bit,64-bit) sur le site du fabricant. Comme indiqué dans les instructions d'installation, le processus requiert les droits d'administrateur, pour ce faire, sous Windows 7, clic droit sur l'exécutable que vous aurez téléchargé et "Run as Administrator" (Exécuter en tant qu'Administrateur). Une fois installé, le logiciel demandera un redémarrage du système et proposera une interface en français. A toutes fins utiles j'ai posté une capture d'écran sur cette page. En résumé, je trouve que ce trackball mérite ses 5 étoiles car à mon sens : - il présente un excellent rapport qualité / prix - il permet, outre un "scrolling" natif, un "scrolling" logiciel grâce à TrackballWorks - il présente un "design" toujours d'actualité - il est compatible PS/2 - USB (adaptateur USB vers PS/2 fourni) - il dispose d'une longueur de câble appréciable (160 cm)

Uso este dispositivo desde hace unos 6 años en régimen profesional en mi trabajo. Es el mejor track ball que he manejado y he comprado este como repuesto por si se deja de fabricar `porque Kesingstone está sacando nuevos modelos con mas funciones pero menos robustos. El producto lo he comprado reacondicionado con defectos en embalaje pero debo decir que el defecto ha sido el embalaje ligeramente abollado. Si trabajas con track balls de media precisión, no lo dudes es un producto inigrualable en calidad/precio.

Objet permet à des personnes qui sont atteints du tremblement essentiel de pouvoir cliquer sur un ordinateur sans utiliser une souris trop compliqué

Having used the Logitech trackball for years, but when it was time to replace Logitech's prices went too high. So, recently tried the Kensington with the Ring and found it to be too wide for most hands here...to the point of being uncomfortable and clumsy. Decided to take a chance on this one without the "ring" and what a difference! The width is just right and the ball moves ever so smoothly and quickly and stops easy too! It is being used on a Linux O/S and absolutely no problems. Highly recommend this mouse. For those who need to know the size width: The narrowest part where your hand lies across the top (to click either left or right side of mouse) is approx. 2.25 inches. Compared to the same brand with "the ring" which is approx. 3 full inches. Also the highest height of the ball on the "ring" model is 2.50 inches and on THIS model it is a half inch lower. SO you can see by these measurements this model is much more suitable for smaller hands, or hurting/stiff hands. Additionally, other reviewers stated that the trackball is loose and falls out...I too noticed that my trackball was not seated all the way in. I took it out and examined it and saw that there is a clear piece of plastic that was stuck on the ball and had rolled to the under side of the ball. It was hard to see because it was clear and had black writing on it and the ball is a very dark gray. I think this piece of plastic had some warning on it -- maybe to remove before use...but it was difficult to see. Now that that is removed the only way I can remove the ball from its place is to turn the mouse over and it gently falls out so that you clean/dust it off. It never just falls out or pops out...unless something is in the way. Its a great little mouse...thinking about getting another one!
