Hi have this mouse for a few hours in operation and it can only recommend. SUPER is suitable for FPS Shooter I'm excited how accuratly the mouse but is unlike my old G602. Meetings I do now more: D. Have the mouse does not buy here and had at home festellen the rights of Glide has a notch or a slight depression. But is not that bad, the mouse still slides Super. Well a bit annoying, however, for 55 but not tragic. Have only ever an eye on the G502 but the G402 is in my opinion much better for first-person shooter of all Call of Duty or Battlefield. Am really excited. And ergonomic mouse fits. Feels super is easily gummed on the sides and is very good in the hand. The button on the side of the mouse near the small thumb rest disturbs not at times I can not manage to connect with this button. And when he is with me anyway without function. From me a strong buy recommendation. In Annex I the illustrative small mistakes I mean by the sliding foot again.
