Welcome and glad you joined.I would really like to try few things first with infinix, like lower pg/vg and/or nicotine to see if I can find the right balance and stick to infinix but if not then I will look for alternatives. Thanks heaps for your help.
My guess that the nic your using is harsh (might ask a friend to test). I would also check and see if PG is causing the harshness. Suggest getting a small bottle of vegetable glycerin and see if your harshness goes away (then add some P/G free nic and see if that makes a difference).
