After the good reviews we chose the model M002S from uping.
Also, my judgment is very positive.
The mouse comes in bubble wrap in a plain white box, with German instructions, fits, you do not need more.
The connection is easy, plug in works.
The mouse itself has no chemical smell and looks dibasic. The build quality is OK for the price since you can not say anything.
She has a good shape, but it is a transition from the MX a familiarization, because it is slightly smaller and the hand by resting just a bit deeper.
My wife finds them even better than the MX because it has slightly smaller hands.
The weight is 104g with much lighter than my old MX, the proud 184g on the scales brings (kitchen scale, both with batteries)
Functionally, it is great, makes me what they should, no jumps, high frequency sound, wireless interference, etc.
For me, a good mouse with good price .... Top
