I have some of these from vaporizerhut, fake pods imo.
What makes you say that, taste/quality of the juice or general packaging etc? Or both?
I've refilled one of my pods with Element Frosty and to be fair, although salts are meant to be faster acting I've found that with the smoothness of the Juul + salts, the amount of nicotine I've been intaking has crept up on me. Couple headaches here and there and bit zapped after using it occasionally.
To be fair I've been on the Juul non-stop at times as I can't get enough of a hit off it. For that reason I want to try the 5% ones to see if there's a marked difference in how I'd use the device. The modest amount of vapour, small size and lack of fuss with leaking/refilling are all nice factors compared to sub-ohming for me.
