I have two X2s and love them, but recently I've been having some difficulties with one of them, getting the USB cord to stay in place for charging or using as a passthrough. If it's charging I have to get it into the perfect position to get the charging light to go on, and if it's bumped or moved even a bit the cord seems to lose connection. It's pretty close to impossible to use as a passthrough, because just picking it up seems to break the connection. It seems to be an issue with the battery and not the cable, because I've tried using a different X2 cable with the same results. If I can get it to charge, it works like a top, but if it's jarred even slightly while charging (which is pretty close it inevitable, given the relatively long charge time and a herd of four cats that seem to need to investigate all flat surfaces on an hourly basis) and I'm not right there to set it right again, all bets are off. :-( Anyone else experience this, and if so, any suggestions for a simple fix?
