I've never used an EVOD, but I imagine it is quite similar to a mini protank 2, where the atomizer screws into the base unit that connects to the battery. If this is the case, I have found that the atomizer will unscrew itself somehow if it is not tightened very tight into the base unit, thus causing leaking into the battery. Make sure your atomizer is not unscrewing loose, and make sure everything is sinched up tight on your units before chucking them.
Have checked the coil and the base multiple times... I now have an EVOD2 and can tell you it is much different. With the EVOD if I disconnected from the battery and blew into the mouthpiece, I would get juice flying out of it, the EVOD2 nothing comes out at all.
I filled up the EVODs and put them on a piece of paper towel, without a doubt the papertowel would have stains from the juice under the head. I have some mini vivi novas that I did teh same thing to and nothing was under them.
Throwing out evod's? Now that is just too sad. Lot of people love them and never have issues. I would have tried removing the flavor wick on top. I use to do that to all of mine. After you get into dripping, all atomizers are ruined IMO. Good luck to ya.
Tried removing the flavor wick, rebuilt the coils, replaced it with cotton, Flipped the gasket upside down, put 2 gaskets in (1 upside down and 1 rightside up), ect and they would still leak like crazy. My guess is those people filled them and vaped like crazy until dry and then only refilled when they were ready to vape the entire thing again.
