I had first issued a not so good review because the mouse where after 5. no longer went. Arctic has however sent a flash a new one. This gives at least 10 stars. The mouse works. Sohnemann is now happy. In addition, you can connect the previous positive reviews in its entirety. Thanks again to Fa. Arctic.
Additional: Yesterday, the new mouse dungeon after a short life (about 6 weeks.) Again their property - out of the blue. Or did I also get just unlucky times and only 2 Monday mice. VLT. but it is better to not save the price. Sorry, but the stars do I have to take it again :-(
