memzuoix Ergonomic Wireless Mouse, 2.4G Optical Cordless, 800/1200/1600 DPI, Vertical Computer Mouse for Laptop, Mac, PC, Desktop (Right Hand, Large) – Black

Very comfortable
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.

Great entry-level vertical mouse for comfort.
I bought this mouse to give my wrist a break, and it really does the job. The vertical shape puts my hand in a more natural position, which makes long computer sessions easier on my wrist and forearm. Setup was instant — just plug in the USB receiver and go. I like that it has adjustable DPI settings and multiple buttons for quick navigation. The grip feels good, and the matte finish keeps it from feeling cheap or slippery.It does run on AAA batteries, so you’ll want to keep extras around, but the auto-sleep feature helps stretch the life out of them. For the price, you really can’t complain — it’s a simple, effective way to try an ergonomic mouse without spending a fortune.Bottom line: Comfortable, affordable, and does exactly what it promises. If you’re curious about vertical mice, this is an easy 5-star starter.

A budget mouse that’s a gamble with component quality
I’ve been using this mouse for a few months now, and I’m happy with the comfort I get from the ergonomic design. So far, I’ve been pleased with the responsiveness, button feel, and battery life for the price. However, like other reviews have stated, I started noticing erratic behavior from the scroll wheel after a while. Scrolling input would get disrupted randomly, and eventually it started reversing input and scroll in the opposite direction briefly before correcting itself and going back to normal. I took it apart and replaced the scroll wheel module with one from an old broken mouse. That seemed to have corrected the issue, but definitely shouldn’t have been a problem in the first place. I think this mouse is better to try and pick up on sale if you’re looking for budget ergonomics. With this flaw that myself and other reviewers have experienced, it’s worth noting that you may be taking a gamble on some quality control issues with internal components.

عيبه الوحيد للان انه مع الاستخدام 5 ايام في الاسبوع لمدة 4 شهور اللون الأزرق بدا يروح

I’ve now had 2 of these. The first one worked until it stopped, when i replaced it. 2nd one doesn’t work at all. Will sample a wired nouse.
