The site is very well-organized and easily searchable. I've been using them for over 2 years and have never had problems with any orders. My packages ship fast and ET communicates quickly with tracking numbers. Biggest Pro: They give very detailed information about every item - how it's used; accessories needed; and any user reviews. The reason I only give them 4.9 stars and not 5 is that they are not always the cheapest and they generally carry certain brands of devices. You won't be able to find a lot of devices like Sigelei or other less-known brands. That said, they are always the first place I look to for major brand devices and my ejuice.
