You're using the Nokia made charging stand right? I was going to buy one of the off brand ones cause it looked cool, but heard they have problems with getting hot.
I'm using two Nokia ones. (one from the ATT sale)
Ehh, just be careful, the generic chinese ones could have quality issues. (I find them to be hit and miss, the hits could be a terrific deal, but the misses...)
Choosing another like an LG or Google one should be just fine, but I'd be careful when picking up a generic one. If the risk of a dud, slightly greater potential of damage is well worth the discount? Sure. I wouldn't do it since those no names haven't treated me too well as of late, but hey, its ultimately up to you.
