Quality of juices, variety of flavors, top customer service, speedy shipping and always exciting vape mail. Extra gifts, samples and goodies with all my orders. They're juice formulation is amazing and I appreciate that they do it all diacetyl free and shoot for AP free as well. On top of that they are paying and testing their own juices and sharing their results with us, the customers. I knew Puffy Clouds was one of my personal favorites and now I wish they had larger than 120ml bottles. If you don't try one of their dessert vapes, you're doing yourself a disservice! I cycle through Slevin, Booberry, BananaRide and Dairyare on a regular basis.
