I am still kicking around whether to buy the provari or a less expensive vv mod. Question is this, I noticed on the provapes website you can add an extra year of warranty for 26.00 bucks. I guess to ask if that is worth it is a foolish question. Just wondered if anyone had sent theirs back for repair and what was the cost? It it cost 75.00 bucks to repairs that is one thing but if it cost 25.00 bucks that is another. I would think the tube would be pretty much indestructible. I am not hard on mods. Just wondering.
