- The body of the mouse consists of three parts (seen in the photo from the side): the base, the upper surface and a narrow spacer between them. So, on my mouse, the problem is that at the junction of the base and spacer, the edge of the base protrudes outward relative to the spacer by a fraction of a millimeter. And this joint is located just in the place that you hold on to with your fingers. As a result, firstly, this sharp edge irritates the fingers, and secondly, it turns out, as it were, a bevel to the top of the mouse, which makes it much less comfortable to hold it. Notice the leftmost part of the mouse in the attached close-up photo. There is no such defect in the photo in the market, so this is probably the problem of a particular copy or batch. In any case, on several M100 and M90 mice that I bought at different times, including at the same time as this M110, this is not the case.
- The bottom LED is not in the center, but on the left (if you look at the mouse from above), and is directed to the side, towards the user (if you hold the mouse with your right hand). Because of this, it is worth slightly raising the mouse to move, and the red spot next to your thumb is an eyesore, and if you raise it harder and turn it a little, the diode shines blinding light directly into the eye. Unlike M100, M90, B100, where the diode is in the center and shines down.
- The scroll wheel is quite smooth and at the same time spins with some effort. Individually, these properties do not cause inconvenience (smoothness is not unpleasant; the force is not too high), but in combination they lead to the fact that the adhesion of dry skin to the wheel is not enough for confident scrolling under the weight of a finger. The finger often slips. You have to put some pressure on the wheel.
