Kensington Pro Fit Black USB 2.4 GHz Wireless Full-Size Mouse - OEM

Pros: It really is full size. I like a big mouse and this fits the bill. Tracking is fine, mouse wheel is fine. Takes 2 standard AA batteries (included), and you can use rechargeables.

Cons: No software to customize the buttons, making it essentially useless for me. The buttons are a bit mushy. Feels too light even with both batteries installed. The reciever is a lot bigger than it should need to be - other brands vary from small to tiny, this one is as big or bigger than most flash drives.

Other Thoughts: I had a Kensington mouse back in the 90's and it was one of the best at that time, really nice clicky buttons that felt great. This mouse feels mediocre at best and without software to configure the extra buttons to the functions I need it's worthless. I'll keep it as a spare for emergencies or give it away.

Pros: It's fairly light for a full-size mouse and the buttons click responsively. The battery life is great (2 AAs), and the on/off switch helps. Never had problems with tracking or erratic cursor movement.

Cons: About a year after buying it, the left button isn't working - sometimes no click, sometimes double. If I angle my hand and really grind down, the button might single click. Dragging is nearly impossible (the button "releases" itself). The scroll wheel is jumpy, too, but that could be dust.

Other Thoughts: I would've expected this mouse to last longer than a year at this price. Granted, I use this a LOT for work, but I'm wary of buying another Kensington mouse for fear it will fail after a year, too.

Pros: I'm not too sure if others have just had bad experiences and I'm lucky for not having one, but this mouse has been great to me. It is actually very fast and responsive, as well as accurate. It fits in my hand like a boss and considering my hands are large, this is a huge plus. It hasn't malfunctioned or derped at all. I think this is a good buy and definitely worth the money.

Cons: It isn't cute and furry?

Pros: large size good for large hands
well designed

Cons: It malfunctioned after less than 3 months. Cursor started spinning madly in mid-battle which got me fragged.
Won't work properly now, sending it back.

Other Thoughts: This is the second bad experience with Kensington mouses.
My Ci65M wireless started oozing a sticky glue like substance from between the top buttons.
I'll be going back to Logitech for future rodent purchases!

Pros: Unquestionably this mouse feels great in my hand. I've got fairly large hands, and this mouse fills it pretty well.

Cons: The scroll wheel has become flaky. If I try to scroll up three notches, it might scroll three notches up but also two down. And vice-versa. Sometimes it adds an equal amount of the opposite direction and I don't get anywhere.

A fresh set of batteries don't make a difference.

I've had this for a little over 3 months and this seems to have developed over the last month or so.

Other Thoughts: I wish Kensington had concentrated a bit more on the quality of it. If it meant it cost $5-10 more, that would be fine by me, so long as it worked properly.

Pros: The fit and feel of this mouse is amazing, especially if your hands are large. It slides well and has a nice USB connector. Also includes and on/off switch.

Cons: HORRIBLE accuracy. The mouse jumps and moves and does whatever it wants to. On small screens, this mouse is so frustrating. I don't if it is the mouse laser, or if it is the USB receiver.

Other Thoughts: Beware, this mouse is huge.

Pros: Great full-sized mouse. Comfortable. No connection problems even though the usb receiver is under the desk and about three feet away. Even though it has extra buttons, they are out of the way. Good thing for those of us that only require two buttons and a scroll wheel.

Cons: The rubber scroll wheel in my mouse is off-axis a little, so every once a turn, the rubber wheel rubs against the inside of the plastic casing. EXTREMELY annoying. ABSOLUTELY unacceptable. I have to apply a right-ward push at with my finger at all times to keep it from giving resistance. Seriously, Kensington... a little quality control please?

Other Thoughts: I'm about to crack this thing open and see if I can shave or sand down the mouse wheel button and fix this. If I can't, the whole thing is going in the garbage. Very disappointed in Kensington.

Pros: Exceptional comfort, performance, and value for exceptional price.
very comfortable especially for large handed people. lightweight but great grip and response.
Great rubberized grip and feet.

Cons: none

Other Thoughts: As others here have said, disable the enhanced tracking feature under mouse options in windows 7 to enable the full DPI potential and make sure the mouse speed it at the highest or close for most response, especially for gaming. Better than much higher priced Microsoft and Logitech Mice which I've owned.. So glad I bought it. No more pain in my wrist, forearm, or hand due to mouse use. It is very ergonomic. If you have a small hand like you are under 5 foot tall and have small hands and feet, this ain't for you, get a small innovera mouse.

Pros: Nice grip, though large

Cons: Goes crazy under OSX, with the cursor jumping all over the screen. I have no idea if it is reliable under Windows, but on several Apple machines, it does not work reliably.

Pros: Large, solid, smooth operation, wireless, comes with batteries (and energizer at that). Simple plug in and play on XP, have yet to see if it works on Win 7. NO HASSLE!

Cons: Somewhat light, switches are TINY.

Other Thoughts: Great Buy, pure and simple...and AWESOME!!!
