The buttons all have a little game, mainly acoustic effect, the operation has no negative effect.
The analog sticks have a relatively large dead zone that despite control to 0% with a program can not be completely removed. A precise navigation of the mouse Zeiges or the crosshair is not possible.
All in all, still a super value for money, at least 4 stars deserved when the gamepad should work for.
As described in other reviews, some keys had contact problems, so initially were not working.
Return was for me out of all proportion to the price, so I can be guaranteed, the guarantee screwed this thing and cleaned the contacts with mineral spirits. The whole repeated twice and now it runs like clockwork.
Since I have received a non-functioning product and this circumstance is no exception, my rating is 1 star. The price / performance ratio of the functioning gamepad is great and is worth in my opinion 4 star.
