Having a carpal tunnel syndrome, and after infiltrating an end in December, I make my re-entry with the mouse, on the advice of my doctor. From an ergonomic point of view, I have absolutely no complaints, no more pain in my hand or my wrist. There was just the 2 main buttons that are hard and rather noisy. In February, surprises, roulette was released after only a month and a half of use. And after verification, it was not reparable. Suddenly, the after-sales services Anker contactee me after my first review on Amazon and I immediately sent back a new mouse. Nothing more concern.
