Bought a elf bar from them this morning on my way to work, they didn't even have me try it before I left to make sure it works and of course it's all a bad puff. It continues to hit itself when I'm not hitting it. Haven't had it for even 6 hours and it's burnt. I've been trying to call them to see if I can come get a new one that actually works but the phone number given isn't even in service. Good pricing but bad product.
