Okay, so I now have 5 Kanger Pro tanks. I obviously really like them, but I have noticed something odd with the packaging. The first 3 I bought a Vape Dojo for 19 bucks a piece. They came in a really nice box that was almost like a jewelry box with nice padding on the inside. Today I was at a place called BmoreVapes. I guess they are a brick and mortar. They sell online, but they have a store in a local flea market. They were running a special today and selling the Pro tank for 15 bucks, so I got two more. These were just in cheap cardboard boxes. The tanks look and perform the same. Did kanger change the packaging at some point? Is one kind possibly a knock off? Is it really worth someone's time to knock off a PV tank?
