This has met and eanred The Rokin seal of aproval for design and reliability. I Just filled it up for a big rough and tough day of sweat and Mud.If it gets a little dent or some little scratches some may call it damage.I just call it beauty marks ..This beast here can take more Than she can dish out,And that's a lot. I liken it to the e-cig world as the American Fender stratocaster to the electric guitar world.It does not look bad with some signs of use and gives it character. At a worst case Scenario All it will ever need is to be resurfaced and polished with my table buffer.After all that it will be mirror finish new again..But I'll probably never do that unless I quit vaping and sell it.. I needed something that could take a beating and I made a decision with no regrets at all. "Dct tank from Health Cabin.Stainless tip from Empire Mods"
