To say the first thing is of course the value of Sharkoon ... The mouse has cost 22 and is well equipped. The packaging is very good. The content consists of the mouse, 6 weights for the mouse, a driver CD and a small Aufbewarungstasche ... I had until now no problems with the mouse, it works perfectly. Previously I had a Roccat Kova [+] and was very small and not as handy as the Drakonia. Have matching the Drakonia mouse also Drakonia Mouse, which combines together perfectly. The mouse I run on my PC at the time without a driver. Strong buy recommendation from me;)
