Since I had every time 30+ for a new mouse to invest no more desire, and I do not play anymore, I have now tried the cheap product. This mouse works and is robust and good for the price. If they eventually break down, it is not doomsday.
Three cheers for the 5 Euro mouse.
When mouse wheel you have to watch something, you is not good with your finger on, it may be that instead of medium-click you get the left-or right-click. Then you wonder why that happens not expect what. But that's getting used to things.
Update August 2014:
The first mouse foot has come loose. Same problem as with more expensive mice: What ever your feet are stuck, for some inexplicable reason, this adhesive soft and dissolves.
I do not understand to this day why mice have ever adhered feet. It should be possible, where the feet are to realize abgegrundete surveys as an integral part of the plastic housing. Instead, the body is always so constructed that it scratches terribly though missing one foot.
