first let me start by saying hi, thanks in advance and im sorry if this is covered a million times. i exclusively use kanger tanks on my Telsa mod and they have been flawless until yesterday. i noticed that one of my protanks was leaking ( its new) and upon further investigating found out it was where the glass has apparently cam unglued. i returned it to my local shop and they said it happens and Kanger has started making the tank with a new sleeve. he gladly swapped it out with a "updated" model. so i filled it up, reinstalled my old head that was already wet ( and recently replaced) and after the first toot or 2 off the new tank it tasted "dry". so naturally i replaced it with a new replacement head. same results. it just seems odd that i have never had this with any of my new protanks except with this one that has the new bottom sleeve. i have flipped and or removed the silicone gasket and it really doesn't change the performance. like i said im using a Telsa and 7.5 watts and the wick is at 2.6 ohms. thanks for any help!!
