@Shit Snacks sucks you're having some problems with your EVO, here is my .02
- Regarding your glass. I don't think it is a crack, perhaps a weird weld? If it functions correctly, I don't think it should be a huge deal....that being said, my Evolver Hydratree is one of, if not the nicest, piece of glass I own. It's blown really thick, and it feels well made in hand......BUT another reason I lean towards that train of thought is that all the percs are perfectly aligned. My tree is perfectly symmetrical, looks the same 360 degrees, I can't find anything resembling what you're describing. I would totally be miffed if it wasn't 100% perfect for the price I paid (or, better term, what its listed at), so I can understand your frustration/concern. Glad to see that it does seem to be working though.
- Regarding a weird smell. Do you have that sleeve on it?
@twosilvertrees mentioned she was getting lots of neoprene smell, wasn't something I noticed but that could perhaps be what you're smelling? It apparently dissipates/stops smelling pretty quickly, but I personally didn't notice it. I don't even know what neoprene smells like lol, so I'm of less help here.
- Regarding an off/bad taste. What temp are you set too? How packed are you loading your ELBs? I find that taste seems to decline a bit when I pack them fully, first few hits taste awesome and then it declines as the center gets over vaped and the sides get vaped (Between 1 & 3 for me on the dial). Try loading less, and setting a lower temp. Or loading less, and keeping the temp up higher. Just, try less and see if that modifies the taste is what I'm getting at. In the video that guy posted above, he was just smacking his little mini ELBs 3 times, so maybe a smaller amount will lessen crappy or off taste. I mention this because when I kick my ELBs, most of it is pretty dark and some of it just isn't vaped as heavy (definitely vaped though), and it seems to coincide with taste/usage for me (I tend to hit it a few times once it starts tasting a little spent, these definitely don't taste great) So if you're doing something similar and getting poor taste, maybe the smaller amount will remedy?
Best of luck to you with it, hopefully nothing too serious
