ALOICI Ergonomic Optical Mouse Vertical Optical Wired Mouse (Size: 90 x 94 x 145 mm) Black 90 x 94 x 145 mm

I was hoping to ease the discomfort I had in my wrist, and this mouse actually made it worse, it started spreading to my hand and arm. However this is probably a personal problem that needs a different solution.However, be aware that the height of the mouse makes it inconvenient to reach it from the keyboard. You'll have to lift your hand above the mouse (or move around it) before grabbing it. This is something I didn't think of before purchasing because this problem doesn't exist with a flat mouse.The second thing I don't like is that to drag the mouse up and down properly, it has to stay at a certain angle, so when I thought I had found a comfortable way to hold it, I realised that dragging it up and down on my desk was making the cursor go slightly sideways too. Maybe there's a software somewhere that can adjust the angle but I didn't care to look further because of the more important problems mentioned above.I also didn't like the position of the scrolling wheel in relation to the buttons.So I am returning it, and going back to a flat mouse for now. Or I might try a different vertical mouse later, that is not as vertical as this one.P.S. On a positive note, the blue light is cool and there's a switch to turn it on and off.

After 2 weeks of using he stop to work.I like the way how its working, position of hand but its a poor quality !
