in every way cheap mouse

Actually, I knew what to expect when I bought the mouse in this price range: a simple mouse with 800 DPI, wired, slightly smaller than the average, thus well suited for the laptop with acceptable processing.
The installation was not, just plug from XP in USB port and off you go, is recognized immediately.
The size is ideal for laptop, yet not too small and it is even people with large hands still comfortably in the hand.
The processing does not cheap impression and for that price all acceptable.
However !!!!! and that is disturbing:
both on my solid black lacquered desk (mind you with grain) as well as other even multicolor glossy smooth surfaces, the mouse reading difficulties and the cursor moves back and forth pointless.
However, on the fabric tablecloth and on Mouse Pads functioning properly. However one wants to avoid Mouse traveling actually lack of space.
Thus, as a conclusion:
Not quite satisfactory but who can live with this deficiency is well served by purchasing.
