We have been using Vapor Bomb for well over a year now. You can customize PG, VG, nicotine. Good range of flavors, and you can customize flavors to a certain extent. Fast shipping, reasonable prices, and good customer service. There were goofs on a couple of my orders, and they made good, no questions asked. They usually send a 5 ml sample (their choice, but usually at the same nic, PG/VG ratios of the rest of your order). We have just started using Mt. Baker Vapor. They also offer customization for nicotine, PG and VG, good range of flavors. Again, fast shipping and very reasonable prices. If your order totals over $15 (not including shipping) they will send you a free 15 ml sample. We have not had a lot of trouble with having to steep Vapor Bomb's juices - they recommend it, but most of the flavors we have had from them were good to go right out of the mail. Some of the ones we have tried from MBV were also good to go out of the mail, others REALLY came into their own after steeping.
