purchasing your highest end mouse has made me NOT want to purchase anything from you ever again. By far the biggest **** i've used in my life. Changing between laptop and pc settings always causes the mouse to have an "error" that can be resolved only through removing an reconecting it again. And then spending a solid minute pressing buttons like an idiot, because some braindead developer decided it would be a good idea to add this *-feature. my left click is occasionally not properly registering for some periods of time, after 1.5 years of use. You charge 200$ for a * like that unapologetically. ********.
