I have recently got a ce5 wickless with a 1300mah ego t (non twist). A mate of mine also got one the same day and his is working fine. Mine on the other hand is working, but it tastes very burnt and dry, we are both using the same juice and we both filled them the same way. I have let it soak overnight still really burnt and dry I cant change the voltage on my battery. Might just order some ce4s from eBay as they seem to be more reliable. Any help would be appreciated.
