The SR cartos will work no problem. The website doesn't say anything about what voltage it is, which is BS, but since its most likely an eGo clone, it's prob 3.4V. If you use LR cartos I wouldn't use lower than 2.0ohm. The Boge 2.0ohm carto will work great. Lower ohm cartos, like 1.5ohm could potentially fry the battery so be careful if you use them.
Crystal clear vaping sells the 2.0ohm and 3.0ohm Boges for a great price. They also have free shipping and give a free syringe with all pack of cartos, and if you get a 15-pack you get a syringe and a free drip tip. They also sell the Ressurector cartos which are very popular and work awesome. their 1.7ohmLR and hold alittle over 2ml of juice. They are designed for a 3.7V PV, like the Riva, kGo, EPower, but they will work on an eGo too. They won't be at full potential at 3.4V but many people still like the Ressurectors on an eGo. Just be cAreful if you do use them. While their less likely than a 1.5ohm to fry your eGo, the Ressurectors still stress the eGo mosfet. Many people use the Ressurector cartos on an eGo or eGo clone and never have a problem, but there is still a chance you could fry the mosfet. My buddy has fried an eGo with a Ressurector, so it is possible.
Like others, I'm not really a fan of Dual Coils either. I use the Ressurector cartos on an EPower and they produce vapor similar tO a DC. And they don't drain your battery like a DC will.
Frankly, I think you could get a much better PV for that price. I would consider maybe checking out their return policy.. I don't like that they don't give any info about that ecig. No voltage, no what the mah of the battery is, nothing. I also think that's very overpriced for something that most likely is just an eGo clone. You could get a real joye eGo for much cheaper than that, or get a 3.7V PV that would be much cheaper too.
A Riva, EPower, and kGo are all 3.7V PVs that have great battery life and hit really well. A 3.7V PV will handle LR attys/cartos better, and also give a slightly warmer vape and alittle more TH than an eGo or other 3.4V clone.
