Hi there. I use a supermini, not recommended. If you want to mix your own liquid you need to get unflavoured nic
juice, PG and or VG and some flavours. The find an e
juice calculator and away you go. Oh you'll also need syringes and bottles etc. Just be careful with the nic juice. Read up on the safety side.
If you want to try a few flavours order some small samples. James at paradisevapeuk.com does some good deals. Send him a message telling him what your after and he'll sort you out.
