Unlike many other retailers, all items labeled as Joye products on our website are guaranteed Genuine Joyetech products. We purchase directly from Joyetech, and all products are shipped directly to us with no middleman. Joye has a reputation for quality that is unmatched in the electronic cigarette industry. Consistent performance and extended lifespan are the norm with Joye products.
We also carry products from other quality manufacturers. These products are clearly identified by manufacturer name. All of these products have been thoroughly tested before we carry them. We have an extensive testing program that we operate in cooperation with our most experienced customers. Well over 90% of the products we test do not meet our strict quality criteria and we do not carry them - we'll let the other stores carry those items. You can find many websites with larger selection, but you won't find any with higher overall quality.
We HIGHLY recommend using the Marineland Blue Foam Rite Size U to restuff your cartridges. Our 510 User Guide explains restuffing cartridges and why good wicking is so important. The Blue Foam is the best wicking material available and is the single most important thing you can do to increase the performance of the 510.
