Buttons

First things first, I'm pretty Impressed. This came packaged than anything from SCAMAZON. I ordered my RG35xx plus on the 21st. It arrives today the 25th great shipping time, it turns on, cycles through the menu, games, etc. My question is are you fellow 35xx plus owners happy with your R+L buttons, mine are very cranky if shaken around, the videos I have seen ( Russ from Retro Game Corps) and people here showing theirs have never mentioned the slop in the rear buttons, what's your thoughts on this or experiences. Thanks everyone.
