The mouse was ordered months ago almost 2 and I must say that I am really happy. Runs super reliable and the color profiles is great. The mitgeliferte Sortware used for assignment, which now does not have to be so special for me, but a plus. The only drawback is that the driver at start-up but needs some time to start up, because the mouse is about 4 seconds after the system is booted, unfortunately a bit uncomfortable that you can not start right away (for a star deduction) otherwise eien super ;) strong buy recommendation.
I also ordered the wireless mouse for my dad for his birthday this is blown away here for 5 out of 5 stars.
