This ergonomic wireless mouse is very comfortable and easy to use for long hours. The design fits perfectly in the hand and helps reduce wrist strain. It connects quickly and works smoothly without any lag. The quality feels great and the battery lasts a long time. Very good value for the price.

I picked up this TECKNET ergonomic vertical mouse because I’ve been having some wrist strain from long hours at the computer, and this design definitely helps. The shape is super comfortable, and I noticed right away that it reduced the tension in my wrist. It feels very natural to hold after just a short adjustment period. The mouse glides really smoothly and the responsiveness is excellent I never feel like it lags or stutters, whether I’m working in design software or just browsing. That said, it’s not perfect. The build quality feels a little on the lighter side, and the button clicks, while quiet, don’t have quite the tactile feedback I usually prefer. But that’s honestly a minor trade-off for how good it feels ergonomically. I like that it has multiple DPI settings switching between them is quick and helps when I need more precision. Bluetooth connectivity has been solid, and the USB receiver option gives some flexibility. It’s compatible with all my devices without any hassle. Overall, if you're looking for a comfortable and affordable wireless mouse that performs well and doesn’t wreck your wrist, this one’s a great pick. Not flawless, but definitely worth it.

My work involves long-time mouse using and sometimes I have to keep clicking mouse for many hours. I started to have problems and pain with my wrist, then I realized that I need to have a professional mouse. It is my first time to use ergonomic mouse. It is very comfortable, especially during long hours on the computer. The design helps reduce wrist strain, and the clicks are quiet but responsive. The adjustable DPI levels make movement smooth and precise. I will keep using it to see if my wrist pain gets relieved. Overall, it is a great option for work or home use.

Works as intended, a little awkward at first but once you get used to it, it is amazing. It very light weight, battery life is dependent on what batteries you choose to use, I’m using rechargeable batteries and haven’t had issues with using it for 5 days a week from 7am to 4pm and turning it off only after 4pm and back on at 7am. Haven't actually had the battery die on me yet as I recharge them every weekend. Design is comfortable for me to use without hand cramps and the accuracy is great. I have not tested the durability but it’s worked fine for the month I’ve had it without any issues with it.

What I don't like: I naturally want to hold this mouse at an angle, the problem is that the screen movement of the mouse is local to the direction it's facing, so if you don't hold it exactly at a straight angle, which feels awkward too me, then your cursor will take a diagonal path across the screen when swiveling your wrist left/right. Instead of moving your hand to the left/right with this mouse, I end up having to move my hand in diagonal directions to move the mouse straight from left/right on my screen. This basically makes it impractical for gaming, and even then it still feels awkward trying to maneuver the mouse under normal use-cases. If you have never used a vertical mouse before, you may not like this, but as long as it's cheap, go for it, maybe you will love it. I had no trouble getting it to connect, all the buttons work, it's pretty quiet, it feels durable. The scrolling speed is ok, but the ergonomics? Well I suppose it's Ergonomic, but it still feels kind of odd, like it's transferring the pressure to another area. The ball of your wrist seems to be where it transfers the pressure, using a pad just makes it more awkward, so if you get this, you will want a soft mouse pad for cushion. (I use a solid mouse pad and it makes it a bit uncomfortable resting the ball of your wrist on it.)
