short but effective
I only used it for a few months because, when I drank a little too quickly, a drop fell into the mouse, and I definitely lost it, but otherwise it worked very well and was comfortable and light, just very fragile... 4 stars. also there's a lot of dust and other residue that settles inside and in the small holes it's dirty, but then it's probably me who doesn't clean enough as there are many mice with holes.
