I've never heard of them and they do seem to have low prices. Not abnormally low though, not when compared to places like elementvape and a few others. For example that site has the rx200 mod for $40, so does elementvape and vape royalty. Myvaporstore, my freedom smokes has the rx200 for less. Maybe someone else has actually used them though and can vouch for how legit they are, whether they're easy to work with or not etc.
