What I really awesome in this mouse find: The freewheel for the scroll wheel. Thus, web pages and long lists can roam super fast and pleasant. The scroll wheel has a lag, so that sets an iPhone-like effect when scrolling.
I was so stunned that I am angry now, having worked for so long with a standard mouse.
Everything else fine and helpful:
USB radio stub. Could get stuck in the notebook in it, but that would not keep in my treatment well long.
Shaping. For a notebook mouse surprisingly large. Rather a not too large desktop mouse. Big enough for my large hands.
Sampling. I had only flirted with a mouse with the latest technology from M $ or Logitech. Price + features voices currently however mE not. The sampling of this mouse works so far on all desk and paper surfaces, I have tried, without complaint and accurately. What more do you need?
Battery life. Not really evaluate after 3 days.
Conclusion: Highly recommended.
