I have two Smoktech AROs and i like them, but lately they have been leaking a lot on the battery contacts. I have to keep blowing them out about once every couple hours. Sometimes more often. I noticed that the edges of the windows are not watertight. I don't see leaking form there, but if i put my mouth on the window on the side and suck hard, i can get juice in my mouth. Is this normal? I'm thinking the lack of a seal there may be negating the vacuum effect which coudl be causing the leaking on the battery. I was thinking about putting krazy glue around the edges of the windows to seal them. Has anyone else tried this? Does it work?
