The mouse texture is nice (despite the current ambient heat) My hands are not big handicap position is comfortable The placement of numerous buttons is decent, the majority are easy to reach The management software is decent although at this reboot mouse starts to vary between all shades of color, I must again specify that the default profile I would like a color void. I do not is the difference between this version (europe) and other more expensive version, but as I have not seen them this is normal Very fast delivery
