no complaints about the delivery and packing list. it has taken a while :) but very satisfied with this mouse. Simple management software, very good ergonomic design ... nothing to fault it really Estetique personally I love it. I have just one comment, I who have always had the habit of using my mouse fingertips, little concern is it takes getting used to take a hand full that otherwise the sniper button n is not easily ateignable but not too far)
