Send Laser mouse with weaknesses

What I liked in the mouse:
- Colors: not only gray or black, but in many different colors.
- Laser: Have a gamer heard that laser mice work better. I could, however, when not surfing verify.
- No unnecessary bells and whistles: Mice have become more and more buttons and functions. Not so here: Just a 3-button mouse (middle button scroll wheel =).
- Huge "sliding" on the bottom: My old mouse (Logitech also) had only quite small "sliding", which took turns then quite quickly. In this mouse, these "sliding surfaces" significantly larger, thus they should adhere better to the mouse.

Now for the weaknesses:
- Rubber on the side: In the early days of the rubber is very pleasant to touch. But then the rubber is by the use of slightly sticky (no idea why). That is not so pleasant.
- Mouse Wheel quitscht: that mice squeak is well known. But of this mouse I did not expect that. And it sucks. After a few days when using the scroll wheel sometimes begins to squeak.

Especially with the last point, I thought it was a defective delivery or a fake. After returning I had to eternally long wait until then the dealer (bdbayer) at the end but did not respond and I had to resort to AZ. Then newly appointed safety at Amazon. But this mouse began to squeak now after 4 weeks. Is thus probably "normal" for this mouse.

Looking for a better mouse I've now the Trust Laser Mac Mouse Scroll ordered white. Has the same characteristics on paper and quitscht not hopefully.
