I have a SMOK T-Priv 3 with a V12 Prince T10 tank on it and I use the Medusa coils (which last longer, has stronger taste, and are cheaper I highly recommend them). I'm looking around and can't seem to find a Prince tank that isn't made by SMOK. I'm wondering if there are any other companies that make a tank that will fit these coils. I just bought a new pack, but the tank itself is old and kind of wearing down a bit as I've had it awhile. Any help with this would be much appreciated.
