In addition to the review. I bought it in April, and now there is a nasty crack at the wheel, apparently this mouse has a sore subject :( I am supplementing the review, today the wheel stopped working altogether and made any scrolling sounds . not even a year has passed Has some pros: It sits comfortably in the hand, is quite light (but if you compare it with the razer deathadder, then this is a brick: D). The ability to connect via bluetooth to 2 devices and switch almost without delay. Minimalistic design. With its cons: It doesn’t always cling to the native bluetooth on my laptop, but maybe it’s a jamb of drivers or the laptop’s bluetooth board
