Have now tested over 2 hours and am beige tert ... why?
Well, as already described by other people, the new surface is eg not as "sweaty"
Also, I find the large-scale solution of the lower slide coating significantly
future-proof as opposed to the small friction surfaces of which MX510
relatively fast side (right) were worn.
The precision and handling are really good, with me nothing rattles.
Sure, the scroll wheel is at the beginning a little more sluggish than usual,
But honestly, when a new mouse ... would be bad if not, do you?
In my previous mouse is no different and was also one is just not accustomed
when the old mouse already had several years from his belt and already had signs of aging.
The cable is thin, right, and a little longer. This is very handy if, for example, a steering wheel
on the desk ekes out its existence and the mouse should remain right (computer links).
So, long story short:
Am fully satisfied, no rattling or other, very precisely, no problems with USB,
simple & timeless design, Plug & Play (no software installed)
