I've been using the GoGo for a few weeks now and love it. I only have one problem. When I vape for an extended period of time, it seems like the juice vapor condenses around the mouthpiece and I get a nasty juice taste in my mouth (at which point, I remove it and clean it and all is well for a while). I think I read somewhere in this forum about this problem but cannot find it. It happens both with the standard tip and a 801 whistle tip. Any ideas?
