Just purchased a Yeti-c from AltSmoke.I don't like it and I wanted to exchange it for a Ego. Rob from AltSmoke informed me the kits are basically parts and they wont except a return on kits. Although their 14 day return policy says nothing about returning kits.(Buyer Beware) I e-mail him serveral times to resolve this but, he does not reply.I hope I can come back here and update this review with a better one from altsmoke.
