is good and safe but also durable so good ??

Positives:
- Is very slippery and extremely flat on the desk
- Mouse moves also absolutely clean and without disturbing or noticeable resistance.
- Mouse accuracy also very good (One notices, however, that the surface of the resolution and fineness of my mouse sensor negative but not noticeable in normal use / play, only if you really pinibel it pays a little bit My mouse is a Logitech Revolution with laser scanning.)

Now for the negative:
- The mouse pad has now shows slight signs of wear at the bottom left where I usually passing loop to the arm. This should not happen after sooooo short time and advertising for the substance. But only slightly, I can not judge how it looks after one year, maybe it will no longer wear out first on.
- Dirt, dust and grease, etc. like the mouse pad, so it already looks a little ugly, if you have to work long and hard on the PC.

Conclusion:
Unfortunately it is not as perfect as it would like, but in any case the purchase and quite small good value for money.
It does absolutely nothing wrong with this mouse pad. Neither optical nor from her material.
Because here and there are a few weak points that could interfere with someone who is quite meticulous, unfortunately only 3 stars.
