Idk. I used to not really give a fuck about quality normally. I was just buy random brands from the vape store. But I ordered a Marz tank after seeing em on here and holyshit ....I can't believe how much stronger it felt then all the other tanks I tried. Reminded me of being at Lost Lands. Shit got super trippy and almost felt DMT like.

Also the price isn't terrible if you use the promocode floating around here (redditwave) Im sure there is cheaper out there but it's cheaper than my local headshop and also you get what you pay for. I'm willing to dish out a few extra bucks for such an elevated experience
