I received my 510 carto's today. They vape great, thanks. These are a bit different from all the others I've used. The filler is different but I read (somewhere) about these and the person took them apart after using and there was nothing burnt. If this is the case, that will be wonderful because the other brand always has a little burnt filler when disassembled after using. I'll post my findings here in a couple of days.
Thanks again Josh. You not only sell very very best
juice (Essence) on the market but your 510 carto's may be the best as well.
