It's the little things that annoy here and let fall back on another higher-priced mouse me soon.
- The On / Off switch under the mouse to be operated only with extremely fiddly fingernail use. Correction: One can hardly use it. (Let's see, how long will the batteries when I always let the mouse to "On".)
- Unlike many optical mice, the "distance" of the optical sensor is extremely poor. This mouse works only on totally smooth surfaces. As soon as it gets a little wavy (leather sofa) sets out the nearly complete sensor. Where other mice to laptop use "on the couch" join any problems, it is in the mouse without a mouse pad almost impossible here. So extreme I've yet seen in any optical mouse.
That's nearly 2 KO criteria for everyday use for me. With 2 stars, this mouse is still well served.
... So here, for those who buy cheap, buy 2x
