Title: a very disappointing product
Review: I've bought this mouse to replace my old, legendryV500 logitech mouse notebook. I did it especiallyto get the laser precision and motion smoothness.The new version fails on the very basics: clicksnot always work and sometimes it misses movements.the result is a very frustrating experience, thatdid not allow me to enjoy the more advanced features.I'm back to the good old v500..
