ProtoArc Ergonomic Vertical Mouse, EM11 NL Rechargeable Wireless Mouse Bluetooth, Ergo Mice with 3 Multi-Device for PC/Notebook/Laptop, 2.4GHz Optical Mice for Windows, Mac OS, White

My previous employer provided a similar Logitech mouse that I loved, but it was pretty pricy, so I ended up ordering this mouse and crossed my fingers that it would work well. Tthe look and feel of the mouse is very premium despite the price. I absolutely LOVE the sound and feel of the click, it has sort of a soft click - if you're particular about mouse and keyboard haptics in that way, you'll love this mouse. I also love that it't bluetooth and rechargeable so I don't have to keep replacing batteries. It was also very easy to connect to my laptop via bluetooth. The DPI button is also a nice feature to quickly change the sensitivity of the mouse.

As I've gotten older (I mean, really old), I began to notice that my wrist would easily become aggravated after only a short time with a "normal" mouse. Thin skin, increased nerve sensitivity?? Who knows... So I tried different types of mouse pads, but regardless of type, my wrist was still lying flat -- and would become sore -- so I decided to try the "ergonomic" ProtoArc Mouse, as it had good reviews & was substantially cheaper than the similar "name brand" ergo mouse. And guess what. It worked - by elevating and changing the wrist's angle - no more soreness/ aggravation. It looks funny & it might take a minute to get used to, but it's comfortable in-hand, easy to set up & works like a champ.

The design of this product, particularly for the price, is impressive. The ergo features are spot-on. The only issue I have in its early use is that it lacks a little bit of weight. While keeping the weight down may have been intentional, the mouse needs a few grams more of inertia to help create a more balanced product. Maybe my hand will adjust to the mass, but for now, it feels like that's what's preventing a good product becoming a great product.

On my initial usage, this vertical mouse impresses me. It is smooth and responsive to commands. It has a handsome fit and finish and feels good in my hand. Its scroll lock is superb, engaging on light finger pressure and moving the cursor quickly up and down the screen without hitches in its get along. The screen forward and backward keys above the thumb rest respond crisply, although I don't often use these tools. The product is attractively priced. It is too soon to know if the mouse it durable, but the manufacturer thinks it is. It offers a two-year warranty. My one criticism is that the dpi key behind the scroll wheel it too easily toggled. The fingers on the left and right curser keys tend to brush across it, sending the cursor on a wild ride into temporary oblivion.

For years I've used the Anker vertical ergonomical mouse, but its build quality seemed to be lagging lately and my scroll wheel would send the cursor in every direction other than the one I wanted. So, this time I selected ProtoArc and it has performed well. I have large hands and when I first looked at the ProtoArc, it said that I should buy the extra-large version. I didn't. I purchased the "normal" version, and it fits in my hand comfortably. One week into ownership, its properly responsive and comfortable to use. If you're looking for an ergonomic mouse, I highly recommend the ProtoARc.

I find the palm rest area gets in the way. If you have smaller hands you might be able to get your whole hand on the mouse, but with my larger hands my palm is half on the mouse and half on the desk. I would prefer to have my hand on the desk so I can move the mouse with my fingertips, but the large palm rest just gets in the way.I also find the thumb position a bit awkward. If my hand is going to be up at an angle the natural position of my thumb is up away from the desk, but the thumb position on the mouse is actually rather low making it a bit of a stretch.Performance wise it is mediocre. I can notice a small amount of latency, but not too bad. Has issues with accuracy of small, slow movements.Feature set is impressive for the price, wouldn't expect something this cheap to have a built-in rechargeable battery.Mouse buttons and wheel feel pretty good. Buttons are actually silent but still have a good feel.

I never write reviews but this mouse is incredible! I’m so pleased with it and it’s one of the best purchases I’ve made for my PC. I can switch between my computer and laptop with a button, and it feels amazing. The designer has outdone himself and I’m going to buy more ProtoArc products for sure

I needed a new work mouse because the apple mouse was destroying my wrist and my thumb and I am so glad I found this one. I have small hands so it fits perfectly in my hand. Set up was a breeze, just connected it through Bluetooth within a few seconds. I thought I would need time to get used to the shape, but it really doesn't take long to get used to because it feels so natural. The buttons are quiet, but still have a slight click which I like. I don't notice any lag in responsiveness. Best part, my pain is almost gone after just a couple of days with this mouse.
