Summary: Generally responsive, and comfortable to use. However, the battery seems to need replacing quite regularly, and occasionally it gets disconnected (unlike my Logitech bluetooth keyboard, which never seems to get disconnected).
Summary: I have an imac i use fir extended periods most days for code and also some light audio/ graphics work. I got this mouse because my old one had died and the magic trackpad is just not that great for everything. I got this mainly for use with Ableton or Blender. PROS: Fast delivery. Easy to set up.
