Kensington Pro Fit Ergo Vertical Wireless Mouse- Gray, White

This review is just my initial impressions after using this mouse just for a few hours. I believe this is a new model, as I could not find any other reviews of it online.I've been using a vertical mouse of another brand at work for about 2 years and decided it was time to get one at home as well. Although the angle of this mouse is almost the same as the other one (A wedge shaped model that is sold under a few different brand names), the feel is a bit different and movement seems more accurate. I think the reason for this is the flare towards the right bottom of the mouse, which keeps the edge of my hand on the mouse instead of dragging on the table. I also really like the scroll wheel, which is a grippy rubber, wide enough that it looks like a ball. The wheel does not do left/right scrolling, but I am not in the habit of using that feature anyway. I don't tend to use the thumb buttons either, but the back button seems to be in a natural spot, with the forward button being a stretch for my thumb.If you haven't used a vertical mouse before, be aware that it takes some time to get used to one. Much of the accuracy of a regular mouse come from wrist movement. Since a vertical mouse is designed to keep your wrist straight, that accuracy suffers. With my other mouse, I've gotten used to it, but still not as good as a normal mouse. I am hopeful that this one will be good enough for photo editing. I'll update this review after using it for a period.Update 12-8-19: Uploaded some images comparing 3 of my vertical mice. The Kensington in the middle, a semi-vertical on the left and the wedge shaped Chinese mouse on the right. The feel of the Kensington is very similar to the mouse on the right, but it is a little wider and my thumb does not tuck in as close to the rest of my hand. Since my thumb is where I am having the most issue requiring a vertical mouse, I am still experimenting to decide which I prefer.

My pinky finger with my old mouse was getting strained and was starting to really hurt. The design of this mouse allows me to fully rest my hand on the entire mouse which is so comfortable

I have found this mouse to be very comfortable to use and have had no problems with its performance (ie. response time, accuracy, etc).I didn't keep track when I installed the current battery I am using. However, I can tell you the first 3 batteries only lasted 8 weeks each. This is a VERY short time in comparison to all the other mice I have purchased. Hopefully my current battery will last longer. Fortunately it only takes 1 AA battery, so it isn't a deal breaker for me. Just mildly annoying. : )

The pictures and product page led me to believe that the scroll wheel was a scroll BALL (like the old Apple Mighty Mouse, which moves in four directions). Sadly, this Pro Fit only scrolls up and down, not left to right. It's therefore useless for video editors and animators.Also, the contour of the mouse is great, but it's too small for my hand (I'm a thin 5' 10" man). When I nestle it into my palm for maximum leverage and comfort, I have to reach my pointer finger back uncomfortably far to reach the scroll wheel. Wish they made these in S, M, and L.

Let's start off with credentials. I work all day long in front of the computer as an animator and I play plenty of competitive online games on the side. I've owned over a dozen mice in just the last three or four years once I really became a computer enthusiast; everything from 13 dollars, to over a hundred, and in all shapes and sizes, ergo mice, to gaming mice. Suffice it to day, I like to think I know a thing or two about what makes a good mouse.But most importantly of all, I've actually owned this exact mouse before, but it went by a different brand name, Victsing, and was half the price of this Kensington mouse when I bought it. I thought that thing was the bees knees when I first got it two years ago, but boy, I realize only now what I was missing out on. The shape and button placement is exactly the same as the previous one, but the sensor, oh the SENSOR!! Good heavens, you really do get what you pay for.Out of the seven wireless mice I now own--with the exception of a wireless gaming mouse that costs NINETY-EIGHT DOLLARS--this is the only one that has pinpoint accuracy, with no stutters and no cursor drift at all, even when subjected to my COMPLETELY unrealistic testing (which is just me sliding the mouse back and forth AS FAST AS HUMANLY POSSIBLE across half my desk. It's a simple test, but it'll VERY quickly reveal an optical sensor's true performance capabilities, as, at higher speeds, a bad sensor will actually stop registering movement, or even literally begin to register the mouse moving in the opposite direction.) Something about the sensor, or the onboard processing, or maybe just the rock solid connection to the usb dongle of this Kensington mouse, makes this thing perform more like a 60 or 80 dollar one instead. It punches WAY above its class in performance, while still keeping all the ergonomic aspects I loved of the previous brand of this same mouse.The weight is very nice, nothing like a lightweight gaming mouse, but that's absolutely not the point of this thing anyway, so I don't dock it for that at all. It glides very well indeed on the dainty little pads, the clicks are wonderfully light, the shape is still as perfect as ever, even for someone who has miniscule hands like myself. The build quality isn't TOP notch, as I can very easily see overlaps or gaps in the plastic seams, but they occur only in places where your hand doesn't touch anyway, and it doesn't even matter, because it's held together very solidly anyway; no creaking of any sort.TL;DR:Of all the ergo mice I've tried, none feel better in the hand than this one, and the performance is way WAY better than I ever expected at this price point. If you're on the fence, just do it. Unless yours arrives broken, I can pretty much guarantee you won't be disappointed.

I ordered this wireless mouse and did not discover that the USB that plugs into your laptop was missing until I needed to use the mouse a month later. It was a few days too late to do a return through Amazon, so I contacted Kensington directly. Kensington customer service was fantastic with sending me a full replacement at no charge. I highly recommend purchasing from this company.

The cursor is jumpy, slow, and sometimes fails to respond.2 weeks and the scroll wheel is failing.....terrible mouse

It is really ergonomically mouse when I am working. I am so happy to bought that one! I recommend it to everyone who wants to buy it

Works great with my small lady hand. It is a nice upgrade from the Anker vertical mouse in build quality. The small lip to rest your pinky makes a big difference.I found it more comfortable than the Logitech lift I briefly tried out in the store, but would still prefer the Logitech MX vertical mouse if price we're not an object. The Kensington is a great value for the price.My only complaint is that the battery it came with was completely dead and I thought the mouse was defective at first. It worked fine with a new battery.

Entrega rápida, pedi quinta pela manhã e chegou na sexta à tarde. Mouse confortável com boa pegada e qualidade de construção. Requer um tempo de uso para acostumar com o formato. Scroll e botões laterais de ótima qualidade, bom clique, ainda conta com um modo de repouso caso você não esteja usando. Sou designer e digo que vale a compra.

Excelente producto, muy cómodo y en lo particular excelente diseño

This mouse was great while it lasted. It fits my hand very nicely and allowed me to maintain a more natural angle in my wrist while using it.Sadly it has become next to useless after around 18 months of very infrequent use as the scroll wheel now simply rotates without actually activating the scroll mechanism, you need to apply pressure to the wheel to get anything to happen, which frequently results in an unwanted middle click.Greatly disappointing from Kensington, as my last product from them, an Expertmouse trackball finally wore out after over 12 years constant use.

I find this shape and size of mouse to be particularly comfortable/ It is ergonomically slanted at the optimum angle of around 50 to 60 degrees, and I'm sure it would suit many other right-handed people too. I've used many, many different mice since the mid-1980s, and am quite sure that this design is one of the very best. The spherical wheel also is more comfortable then the usual cylindrical-shaped ones that have a flat surface. Kensington also offers left-handed versions of this design.
