I picked up a pack of sapphires from GotVapes and I'm surprisingly impressed with them. Keep in mind this is coming from a picky, heavy CE2 user. Right out of the box they seem pretty sturdy. The black parts of the body are just a sticker wrapped around it which peels off easily. It looks good either way to me. The cap has a nice snug fit, the fill plug is easily removed for filling and it fills very easily. I use a home mix liquid that's a 70/30 PG/VG mix. Vapor production is great, lots of plumes. It's a bit surprising how much considering when you hit it, it doesn't really feel like you're getting anything. That said, the vapor is very cool and light weight, flavor is ok, not strong like a CE2, but it's there. Heavy chain vaping will make it run dry. I've found that leaving the fill plug out keeps it from running dry, probably a vacuum lock effect, but obviously you wouldn't want to leave it on it's side like this. I have flooded it, but it amazingly doesn't leak into the connect. It leaks into the air slot on the side and creates what I can only describe as a .... effect. I'm no pot head, but I know what that gurgling sound reminds me of, lol. All in all I think they're a good vape. Capacity could be better and maybe wick exposure, but in the end this is the first time in a very long time that I've been able to pull something out of the package and just use it without any glaring issues. Great product! Thanks Chris and Dan!
