Well nautilus BVC ones was ok before i washed them, then they got this chemical taste. After, i bought new coils, but they sent me BDC not BVC i ordered and those all have this chemical taste no matter how i use them. I tryed to wash new one, tryed to drag before pressing fire few times and added juice right into another coil but nothing worked... Meanwhile, i never had any problem with iClear 30, even after washing them 3+ times :) Not sure i wanna try something else from Aspire so Kanger it is, i do regret that i bought Nautilus not Protank before...
