I have owned my vtr for 3 weeks now and love it, but this past weekend it failed me and I have yet to get the issue resolved. All of a sudden my vtr wouldn't turn on with fresh charged batteries in them. I found out that I would have to press in, on the battery door, to get a solid connection for the vtr to turn on. Apparently somehow, the battery bay is not getting a solid connection from the batteries, I have never dropped the vtr. I dont know how this issue all of a sudden came about. I talked to my local vape shop, where I got the unit, and the only thing the manager said is that he could take the unit apart himself and see if he can figure it out, and if he can't he will replace it. Innokin themselves were no help. Anyways, the manger at the local store has never taken it apart so I might as well do it myself. Any head about this or know how to fix this before I take it apart? I assume I just need to take the bottom off and see if I can tighten the battery door?
