Check out the clones on e-bay and compare. I supposedly purchased legit one too from a B&M months back but I don't know what version. I'm just trusting my local B&M because they claim they do not sell clones. It's my only legit item, and the JPGE logo etching has differences with the clone closeups on ebay. Sometimes the deck looks a little different too, like center post looks raised compared to the negatives. (all 3 posts in mine line up even)
Although looking back I kinda wish I did just buy a cloned
rda. Like you I paid 70$ couple of months back. The packaging was a regular small plastic baggy and it came with no spare O rings/screws/no drip tip and the top cap had light scratches on it. Even FT Clones give spare o-rings, screws, and an additional drip tip for some of their
rba clones that cost $23 and under! Only thing that might have certified the product was some flimsy square black JPGE print out that could've been reprinted.
