It's not the most feature-filled mouse, I must admit. It doesn't have additional weights you can put in, or a dozen buttons. It's also rather light, and some people prefer a heavy mouse, or at least one with a little heft. It's also expensive for what you get.

Those criticisms aside, however, it does one thing very well- it points the cursor. The buttons are not too stiff, and the mouse is just the right size (I prefer them slightly on the 'full bodied' side, unlike some of those mini-mice you can get today). The scroll-wheel works well. Once you get used to the back and forward buttons (slightly further back than I'm used to, and relatively small), they're easy to press and not stuff. The mouse is responsive, tracking is accurate (I use it without a mouse-pad, on a textured wooden desk) and it comes with an adequately long cord.

All in all, quite a nice mouse; now, if only it were priced at $10 instead of $20.

HASH(0xa5d78054) out of 5 stars Required tinkering; but worked great after set up USB mouse. Oct. 16 2010
By EleganzShopper - Published on

This mouse works great on my PC (Dell 400, Zino PC) with Ubuntu, Debian and Microsoft Windows Vista Operating Systems as well as on my Mac (eMac G4) using Debian(GNU/Linux) and MacOSX Operating Systems.

The mouse did not work out of the box (for my first Pro Fit); I had to tinker with the mouse preferences which is something I did not have to do with my other mice. It was worth it though cause this is a comfortable mouse; larger than the Kensington "mouse in box" series of mice (I have one and I like it) and it is larger than the DeathAdder by Razer. This mouse is about the same size as the Kone+ gaming mouse made by Roccat. It is also taller and about as wide as the Mionix Naos 5000 gaming mouse.

The Kensington Pro Fit mouse has five controls set by default. Until I set the mouse preferences for 5-buttons instead of 4, I did not have cursor use of the mouse; but the other four functions worked. I did set other mouse preferences in the different operating systems and window managers of Ubuntu (Xfce4, Enlightenment,etc.)and of MS Windows Vista. I found that once I set the correct mouse and pointer preferences this mouse worked flawlessly and easily.

It has been one of my favorite mice as far as comfort to use goes. It works fine. When my dog bit the Naos 5000 gaming mouse in two I was back to using the Pro-Fit mouse. It was well worth the cost. Until I set the preferences of the mouse on the PC I thought I had a faulty mouse (cause it would only light up rarely and work for a few seconds with partial functions. So I am glad I had the weekend to tinker with it.)

This is a comfortable to use mouse though still not as large as I would like for my hands. I would only really call it a medium sized mouse in terms of width.

When I first started using this mouse with Ubuntu I had to have a second mouse plugged into the PC to use the new mouse (only worked partially; until I set the preferences.) I found that I had to start the PC without the mouse plugged in. Then plug it in (having already set the preferences before. Then in Microsoft Windows Vista the OS searched for the driver. For both OS (Windows Vista and Ubuntu) it required some time for the mouse to be recognized with all five function. I left it plugged in and I used my other mouse; eventually the last function (cursor) of my first Pro Fit worked all the time. So at first my first Pro Fit only worked off and on with the cursor; but eventually all the functions worked after I had set the correct preferences.

Update October.28.2010. I got my second Pro Fit mouse and this one worked correctly right out of the box without having to do anything with the preferences. I plugged in this second Pro Fit mouse into my Mac (eMac, G4 1.42GHz 10.4.11 OSX Tiger) and it has worked flawlessly. I did order some polytetrafluoroethylene (PTFE) feet since they really make my DeathAdder mouse by Razer feel so elegantly smooth when I move across the mouse pad.

I like the feel of this mouse on the SteelSeries Qck Mass mouse pad; but I also have a smaller Fellowes mouse pad which gives more resistence (drag) and therefore more control than the Ock Mass pad. Still I want to try the PTFE on the mouse feet for more facile movement and control.

I read that this opitical mouse has a 1000DPI. It moves fast and is accurate with my operating systems whether I play games such as Alien Arena (point and shoot fast) or using it for every day uses.

I did find the Kensington Customer Support helpful when I called in about my first mouse. Their telephone numbers are listed on their website (toll free.) I found the site when I registered my mouse for it's warranty.

Updated September.19th, 2011. This Pro-Fit mouse still works great. I use it when I want to use my Ubuntu computer operating system as my Kone+ does not work with Ubuntu OS. This is a comfortable to hold and use mouse which works good. It is not a gaming mouse.

HASH(0xa61d642c) out of 5 stars This is a great mouse Nov. 6 2009

Kensington is not the first, second, nor third name I thought of when I needed a mouse for my Mac. I started with Logitech, which was expensive and their software was a bit buggy. I also had quality issues with them. I wouldn't want to install a Microsoft mouse on a Mac, not even as a joke. I've had horrible problems with Belkin mice. And, I tried a 'gaming' mouse with fancy software - which was very expensive, worked for a while.

I was ready to try anything. Kensington was receiving good reviews on their other mice, so I went with the pro fit. The price is amazingly affordable. It doesn't require any software drivers - which is perfect because special mouse software is nothing but trouble.

I plugged it into a USB hub, giving it the so-called acid test. It works great on the hub. The movement is smooth and is a great fit with the Mac mouse settings. The fit in my hand is perfect - so comfortable. I can drag and lift the mouse easily - it's very light with rubberized sides. I can pick it up without accidentally clicking on the side buttons. It's a no-nonsense, just plug it in and you'll be happy type of mouse.

On top of this, they give you a 5 year warranty. For this price, I would just buy three in case the first two mice break. You will not be disappointed if you have large hands. Small hands? Maybe look at the other models first.

HASH(0xa5d74948) out of 5 stars Finally a Mouse for a man's hand. June 10 2011
By aman4allseasons - Published on

I'm a gamer who spends most of the day playing games on my PC; ( I'm retired) so a comfortable chair, a high resolution monitor and a comfortable mouse that reduces wrist and finger fatigue is important.

After using these stock mouse that computer accessory company's have been sleping for years, finally a mouse comes along that is designed for a large mans hand.

This mouse is great; it's comfortable and reduces fatigue so I can play all day long; and, I had no installation issues with this item. The "FOUND NEW HARDWARE" message popped up and the computer did the rest.

So if you have a large hand like most men have, this is a must.

HASH(0xa819fdf0) out of 5 stars Ergonomic full-size mouse Oct. 3 2009

A great deal for $20. A full-size mouse that is designed to fit your hand and allow it to curve comfortably. The buttons are not stiff, but they do make a clicking sound - this doesn't bother me at all, but just be aware if you're sensitive to that kind of thing. I highly recommend it.

HASH(0xa5d78f3c) out of 5 stars Great mouse Dec 3 2009

I like this better than Apple's mouse. It's larger than most mice, which is more comfortable for me. I usually had to accentuate a right-click on Apple's mouse, and this one I don't. The Apple mouse trackball got quickly dirty and unusable. I never could clean it well enough, as the Genius Bar recommended. This one has a trackball that's larger and gets better traction. I don't expect to ever have a problem with the trackball. Overall, this mouse is very comfortable. It seems to be well-built; however, I've only had it for a month or so. I've worked with computers for almost 20 years and never used a better mouse than this.
