The led lights are cute but after a week the mouse started lagging and the shape is too big for my hand. So it helps with my wrist but now my thumb is cramping up, and since it’s only one sided I don’t have the option to switch hands when one hand gets sore.
Basically as advertised, and after using it for a couple of days, it works great. The plastic casing of the mouse does feel very thin and cheap, but for the price you couldn’t really expect much else, and that likely won’t affect performance. Arrived with small discoloured smudge on the edges and front of the mouse that I haven’t been able to clean off. But they’re minor.
