Many times I've seen knockoffs at Discount Vapers. You have to be VERY careful and read the description.
The description for what I bought said KANGER Evod replacement heads. Really, it's OK though...the one I've tried worked.
I've got a blister pack of 1.8 ohm and another of 2.2 ohm one bought online and the other from a B & M. I have yet to see one with the ohm rating etched or printed on the head. This is also true of the 2 that came with my Protank kit. Here's how the blister packs are sold.View attachment 224460
That's strange...my Protank heads that came with my kit, BOTH have the ohms etched on them. The blister pack that I got for the 5 Evod heads from DV, did NOT come in a package like you showed. Like I said though...it's all good. Just wanted to point that out is all.
