So I bought one of these about two months ago to use with my eleaf istick 20 Watt. When it arrived the glass was cracked. I msgd the company I ordered it from and they sent a replacement as this is apparently normal. I've had the second one now going on two months. It's great! There has been NO gurgling... NO leaking... the only thing is the spit back can get pretty bad...But I love my juice so much this doesn't really bother me lol. So things have been great. Great little tank...than last night it breaks. Not only does the glass crack, But the bottom was screwed on so tight, that in the process of unscrewing, the whole thing came apart. When it did, the cracked glass broke completely... and guess What? It's plastic. 100% undoubtedly plastic. I went back and looked it up and it is absolutely SUPPOSED to be glass. But mine plastic! I don't know if It's just mine or if this happens to a lot of people. Has anyone else noticed this about their Eleaf GS AIR???
