as of now people are buying at thier own risk, people are selling 4 different versions and most of them are bastomizers and then the few that have the real ones are at 2.5 ohms or in that range. so thier results are a toss up.( some have the real ones at higher ohms but god knows who).
This isnt the vendors fault, we all know where the blame lies.
The ones i have, the real r4, the same one that i sent to 16 people, no glue, full sleeve, no afl filler, and proper ohms at 2.9 to 3.1 , those have been working very well. are they perfect??, NO, are they alot better then other revisions, I believe so. why arent they perfect? because while they wick much better and i will also use them as is, the ptb makes them that much better. so im being picky in that sence. other then that it doesnt leak, fits all my mods and are at the proper ohms. so not much to complain about.
