I bought it because I am a graphic designer and I work many hours with a mouse. I have a very small hand, and this caused me carpal tunnel syndrome because with no mouse my hand did not have the correct position. The pain and numbness decreased when small laptop mice finally came out. When I got this mouse, which has (finally) sizes, my hand immediately felt numb, which means that something different happened with the position of my hand. This changed in about a week. It is not easy to get used to using it, especially for precision work, but now after 4 months there is no issue. I recommend it. It also has many buttons that you can customize shortcuts and it is incredibly helpful in our work.

For those who have tendonitis problems or for those who do not want to acquire it, this specific mouse is suitable for long hours of work. The truth is that it takes a little time to get used to it, but then you can't part with it. I highly recommend it. It has an on/off switch underneath, although I would prefer it to be automatic for battery saving. The surface I use it on is wooden, slightly glossy, and it works with absolute precision without any problems. It has software that allows you to customize how you want to use all the buttons (it has 5). Also very useful is the Pointer speed located next to the main buttons

After spending several years together, it's time to replace it with an identical one.
The ideal mouse for graphic designers and those who work long hours.

It helped me a lot with the problem I had in my wrist!
It wasn't the typical carpal syndrome but nerve discomfort in my hand and numbness because I had to use different mice for hours every day!
100% improvement! Idea and creation of an American College after researching the effect of mice on the wrist.
At first, the feeling is a bit strange but you get used to it very quickly. Relief is noticeable from the first days!
I highly recommend it not only to those who have a problem but to everyone in order to avoid the problem!
