I love this mouse! I was used to carpal tunnel from previous mice, and my fingers would start cramping when I did a lot of editing at once... I'd have to rest them... stretch them out... then start again. This mouse has yet to cause my fingers to cramp even after hours of use. It's very responsive and recovers quickly after sleep mode.The only thing, and it's not a defect, but my index finger occasionally gets lazy and presses the clicker directly below it at random times. With a regular mouse this was rare, but with this one and it's 2 inch height, it happens more. Not a huge issue considering I no longer have carpal tunnel in my mouse hand! I don't use it for gaming, but do use it for meticulous photo and video editing. Awesome feel and comfort and response! Love it!* Update * After a couple months use, I am noticing the cursor lagging a bit, and stopping some. Occasionally it'll just stop mid movement. At first I thought it was my finger slightly slipping, but it's happening a lot. Dragging something across the screen and it'll let go mid-way. I tried changing the batteries, no difference, it's becoming annoying. I haven't had one of these vertical mice before, I'm wondering about getting another one to compare... will update one way or the other.* Update * So I purchased another very similar mouse to compare, the "VicTsing Ergonomic Mouse". Turns out being installed UNDER my desk was causing my "lag" in the Memzuoix. Now moved to a USB hub beside the mouse and w the lagging behind me, I continued to compare the two. The VicTsing doesn't feel nearly as stout as this Memzuoix mouse. There is just something that feels "cheaper" w/ the VicTsing. Advantage = Memzuoix Even though they look exactly the same, the VicTsing is ever-so-slightly taller, and I like that better for my large hands. Advantage = VicTsing However, the VicTsing doesn't have the extra "rubber like" grip where the thumb goes. Love that on the Memzuoix. Advantage = Memzuoix The buttons on the Memzuoix are ever-so-slightly more sensitive which means I get a lot of "accidental presses" from resting my finger even slightly and accidentally pressing a button, not so on the VicTsing. Advantage = VicTsing Now that I fixed the "lagging", they are equally responsive and accurate. Advantage = none They are about the same price, though the Memzuoix is slightly less. Advantage = Memzuoix I doubt either are made in USA. Advantage = none So which will I choose to use? I like the rubberized thumb grip, but like the ever-so-slightly taller profile of the VicTsing. With my bigger stronger hands and less accidental button presses, I will be using the VicTsing. If you don't have big hands, I'd recommend the Memzuoix.* Update * After a few weeks using the VicTsing, it's scroll wheel started to squeak, and it started missing clicks, I had to re-click often. Back to using the Memzuoix. Working flawlessly so far.

This mouse if wonderful! So much more comfortable than a regular mouse.

Exactly what you need, no more, no less. Ergonomic and comfortable. Great wireless mouse.

マウスにしてはややデカく感じ、形状的に違和感があり…ただ使い慣れてくると腕が疲れない。特に慣れてきて長時間使うと結構楽なのがわかる。事務仕事で長時間マウス使う人にはオススメ。
