Ergonomic Vertical Mouse,KKUYI Upgraded Rechargeable Optical Wireless Computer Mouse,2.4G Bluetooth/USB Mice with 6 Buttons,800/1200/1600 DPI Levels,for Laptop,Desktop,PC, MacBook Compter Mouses

I was having lots of problems with my thumb when using a traditional mouse. Co worker had a different brand but same concept. She let me borrow hers while on vacation. My thumb pain was gone in a week. That’s was 5 years ago. I haven’t had pain since. Switched all my mouses out. It might feel different at first but it will feel natural in a few hours. Now using traditional mouse feels uncomfortable. This is lightweight. Just perfect.

It definitely takes some getting used to. Not only is the angle you hold it different, but you have to change how you click the buttons to minimize pushing the mouse to the side and accidentally dragging instead of clicking. Once you do get used to it, though, it's much easier on the wrist than a normal mouse. Overall quality is good. The shape is comfortable, the option for different DPI settings is nice, and the buttons don't feel cheap. The sensor is decent, and I don't notice any input lag. I only have a couple relatively minor complaints. The scroll wheel is pretty stiff, which makes it especially difficult to wheel-click without moving the mouse much, though I'm getting better at it over time. Also, the forward and back buttons behave inconsistently. Some programs read them as you would expect, and some programs, like my browser, read forward as back and back as forward. I'm not sure what could cause that, and I guess it might be an issue with my computer for all I know. Overall, it's a great ergonomic option, especially at under $20.

I bought this for personal use and use it every day. It's extremely comfortable and I like that its batteries are rechargeable. When they run out of juice the mouse can be used while it's plugged into the charger.The only thing I don't like is that there's too much friction between it and my desk surface. By this I mean that you have to give it a nudge to move it, and this often causes the pointer to overshoot whatever you want to click on. This is annoying but not so much that I'd consider returning it.Comparison: For work, I have an Adesso wireless erg mouse provided by my company. Since I'm working from home and use both mice on the same desk, I know that the friction issue is with the mouse and not my desk because the Adesso glides like it's on ice. But the Adesso also costs twice as much, and uses two non-rechargeable AAA cells that die abruptly. Keep a wired mouse handy if fresh batteries aren't available.

This is still my mouse of choice. There are 2 small changes to the latest version that make it feel cheap compared to previous versions. The 4 pads on the bottom of the mouse have been made so small they are almost non-existent. This means the mouse doesn't glide as nicely as previous version. Also the scroll wheel material has changed to a cheaper material which is harder to grip.That all been said I still feel like this is the best deal out there for ergonomic mice. Without those changes it would be 5 stars

This is my 3rd 'vertical' ergonomic mouse similar to the ANKER vertical mouse design, my second with the Li-Ion battery.Unfortunately, there's one glaring weakness - the scroll wheel is squeaky, and not smooth to operate. I've had this mouse for 2 months, and it hasn't gotten any better.Other notes -The forward / back buttons on the side are also reversed to previous vertical mouse models that I've used. On this one, the button closer to the front of the mouse is the BACK function, and the button closer to the palm is the FORWARD button. I'm only giving this mouse 4 stars for ergonomics because of this weirdness.The battery life is good for about a week of drafting work. It recharges quickly. The last vertical mouse I had lasted a little longer between charges.

This mouse has been a life saver for my carpal tunnel. I love that it is rechargeable. It does have a function where it goes to sleep after not being used for a period of time. Took me a second to figure out you have to click it to wake it back up.

Bought this mouse to replace another model since the wheel went out after 2 years, and within a month the wheel is going out. See how long it lasts but it squeaks when scrolling and rubs on parts on the inside, which is annoying.

The first time I used it, I thought I'd have to send it back because it didn't seem to fit my hand. Since the user manual says getting used to it can take a few days, I decided to give some time. The 2nd day was easier and 3rd day, I've decided to keep it. It is more comfortable than a regular mouse. My only problem with this mouse is that it really isn't made for smaller hands, so it's more of an adjustment for me than it was for my husband. I had to disable buttons 4 & 5 because they are right where my smaller hand fits. Not problem for me since I don't use them anyway, but something for others to be aware of.

Bought this looking at international reviews. I wanted to try vertical mouse due to wrist strain while using normal mouse. The mouse just got delivered but it feels very cheap. The buttons don’t look good and there is a very distinct cheap plastic smell to it, typical of Chinese products. the dpi button seems to be clumsily attached.. and the entire mouse seems to be clumsily glued together with parts rather than a whole mouse.. I don’t have confidence that it will last. Retuning it now. Better to avoid. Not worth the money..

The product description says it is silent, but there is too harsh click noise. The click is hard as well. Not worth for 1700
