Kensington Pro Fit Full-Size Wireless Mouse (K72370US),Black/Silver

This is the second of this same mouse, my first was purchased over 7 years ago and I've been using it ever since, including during the pandemic 2 years of WFH. It still works great, I just have a second work station at home. I love love love it, because it is comfortable to use no matter how many hours you use it. I've seen other reviews that criticize the large size, but the large size and the ergonomic shape is why it is so great! I have smallish hands, too. For me it's a joy to use, and the price has come down quite a bit since I bought the first one in a brick & mortar. I'm thinking about buying a third to take to my workplace. Sure, they provide me a mouse, but not the best mouse ever.

Very nice mouse. The mouse is taller than most, and wider, so it fits in my hand very well. The tallness allows me to rest the palm of my hand on the mouse. The bottom profile is larger than most mice, so it glides a little slower than I am used to. Therefore, I increased the cursor speed to maximum and it works great. I like the side scroll feature of the wheel and it has a very nice weight to it. Oh, and the wheel is rubbery, not hard plastic. The best thing is that the dongle is large and has 2.4 GHZ wireless, so the signal is nice and strong. I had tried using an M510 Logitech wireless mouse with my PC, but the wireless dongle is just too small - that mouse is for laptops and not PCs. Also, this Kensington mouse was just knocked on the floor but took zero damage. I really like the size of this mouse. My hand cramps easily and this mouse is great!

At 5" long and 2" high, this is the BEST full-size, std. mouse I've been able to find for large hands. The Logitech M705, while having more programmable buttons, is just slightly smaller. Note that the Amazon size/weight description is bogus; dimensions are about 5" long, 2" high, and 3-1/8" wide at its widest point. Not even the box it came in is 8.9" long! The weight is a typo at 0.01 oz as well (just silly). Pros - Good battery life. Mine lasted years. - FULL SIZE fits large hands (ergonomic and comfortable). I suspect some reviews are for the mid-size equivalent. Be careful when ordering. - Top button behind the scroll wheel sets the dpi sensitivity dynamically, which is nice. - No custom driver; uses std. Windows HID driver. Only reasons I didn't give it 5-stars: - Had one at work that the scroll wheel broke on after a few years of use. Bought a replacement at work and one for home. We'll see how it goes. - only two thumb buttons for page-up/page-down (don't always work as expected). Not programmable. - No custom driver; uses std. Windows HID driver. - Dongle is a bit large on the wireless version, but on a desktop machine doesn't really matter. - Dongle and mouse have to be "synced". Only once, or after changing batteries, but why? Overall, BEST standard mouse for big hands without going to a funky vertical mouse or trackball. UPDATE: I'm not dropping my rating because the Pros above still hold. However, this thing just randomly SHUTS OFF while I'm using it. Nothing I do will wake it up (wiggling or button clicking) and I'm using it at the time, so it is not just going into sleep mode; it's more like "dead mode". I have to open the back, pop a battery and re-insert it - then the mouse wakes up and behaves normally. It seems to happen when I'm using the scroll wheel to scroll through large PDF documents in Acrobat Reader, but I can't be sure this is consistent. It's pretty annoying as I really like this mouse otherwise.

I have generally stayed away from wireless mice for various reasons.. bad tracking, excessively expensive, lack of back and forward buttons, internal batteries that can't be removed and charged by myself, mushy or otherwise annoying to use scroll wheels, etc. My all time favorite wired mouse has been the Logitech MX-518. I must say that this wireless mouse has perfect right handed ergonomics, tracks well on the bed sheets I use it on, uses an AA battery which lasts much longer than AAA batteries and puts my eneloops to work, and seems to have similar button feel to the MX-518 with a nice scroll wheel as well, along with perfectly positioned back and forward buttons. I don't know if I'd use it for gaming, I'd stick with the MX-518, but for general browsing it's perfect, and the price is right. One thing of note... this full size mouse is large, larger (more like wider) than an MX-518. If you want a mouse similar to the size of a typical mouse, go down a size. If you are right handed with nice wide hands, you'll like this mouse.

Update: I came back to remove a star. The left button sticks terribly and picks things up and moves them around that I don't want to pick up and move around. The scroll wheel is still terrible. It's time to start looking for a new mouse. Original review (three stars): I've had this mouse for a year and half now and I don't know how I've lasted this long. I keep plodding along with it because it is a comfortable mouse to use and it's hard to find a mouse that works well for large hands. But the scroll wheel is terrible (it literally zooms out when you want to zoom in, or moves you up a page when you want to scroll down). You have to click to wake the mouse up after about five minutes, which sometimes causes me to click on things that I don't want to click on. And when I have another thumb drive plugged into the space next to the USB connector for the mouse, I have a hard time getting the cursor to move at all. It just freezes. I should have returned it when I had the chance. Three stars is probably a generous rating.

This is very much a Goldilocks story, with the Pro-Fit Mid-Size mouse being too small, and the Pro-Fit Full-Size mouse being too big. For reference, I’ve been using a Microsoft Explorer Mouse model 1362 for over 10 years. I love every aspect of it, particularly how comfortably it fits my hand. I needed another mouse for an additional computer, and decided to try the Kensington Pro-Fit Wireless models. I first went with the Mid-Size mouse since I wear a medium size glove and there were some complaints about the Full-Size model being too large, even for large hands. Unfortunately, the Mid-Size mouse was just too small for my hand: both fingers projected over the front edges of the top buttons (my middle finger by over 5/8” from the front edge of the right button), making use of the scroll wheel and the button behind it very awkward. Also, my thumb rested on the front edge of the front side button, making both side buttons awkward to use as well. Plus, the contour of the top of the mouse felt very unnatural, as I had to flatten my hand quite a bit to rest it fully on the mouse. I then tried the Pro-Fit Full-Size mouse. Unfortunately, it proved to be too large. My index finger was 3/8” short of the front edge of the left button, and I couldn’t extend my thumb far enough forward to reach the front side button. And, as with the Mid-Size mouse, it had the same unnatural feeling top contour, which required me to flatten my hand to fit. Since Kensington doesn’t see fit to provide the dimensions of these mice I thought it would be helpful to provide some elevation and top photos of both mice using quadrille (5 squares per inch) paper for a background. I’ve also included elevation photos of my Microsoft Explorer mouse for comparison. Briefly, the Pro-Fit Mid-Size mouse dimensions are: 4.25L x 2.7W x 1.62H inches. The dimensions of the Pro-Fit Full-Size mouse are: 5L x 3.2W x 1.8H inches. (Any apparent variation in size from one view to another is due to parallax.) Note that the contour of the top of the Explorer mouse is a smooth, almost constant radius curve, both longitudinally and laterally, with a mild drop-off to the right (viewed from the rear). This provides a very comfortable fit to the relaxed human hand. In comparison, the top longitudinal contour of both Kensington mice is a much tighter radius curve for the rear half, becoming almost flat for the front half. There is a pronounced longitudinal ridge down the center, and only a very slight drop-off to the right (when viewed from the rear). That top contour does not fit my relaxed hand at all and, as I mentioned above, I have to flatten my hand quite a bit if I want it to rest on top of either Kensington mouse. On top of the ill fit of both, the Pro-Fit mice scroll wheels have very pronounced and coarse detents, giving them a very rough and cheap feel. Particularly in comparison to the very smooth feel and fine resolution of my Explorer mouse. Both Kensington Pro-Fit mice are being returned, and the search for the perfect mouse continues. If only Microsoft still made their model 1362 Explorer mouse. (;^)

I love this mouse. Perfect size. The mouse goes to sleep to save battery life when not in use.

I have large hands and it’s a great ergonomic mouse! It fits my hand well and the functionality is perfect!
