The VP2 chargers are excellent quality. The VP2 was the very first XTAR charge I ever purchased, I wouldn't recommend using it. Contact the seller, as soon as possible, to see about getting an exchange - or to, at least, see what they have to say about it.
I have two of these VP2s, and about a dozen other XTAR chargers
, and have never received any of the chargers with this kind of liquid on them. All of my purchases have been directly from an XTAR distributor (and there's a store about five minutes away from me, so it's very convenient), and they've always taken care of any problems I had with a charger, immediately. Great service :-)
The only thing you should have to remove, from the charger, is the little plastic protective film that's over the display - typical of electronics items with displays on them.
