I was using the istick 50w with the eleaf gs tank atomizer when I got the burnt taste. I had no spare coils for it so switched to my nautilus aspire tank. Still had the burnt taste, 3 brand new coils later I decided to try my istick mini and the burning is gone. Seems the problem is with the istick 50w, which is odd as it is fairly new (had it for about a month) and has been working great up until now.
If anyone can offer any advice as to why this might be and how it could be fixed it'd be much appreciated. I'm going on holiday on Saturday and really wanted to take it with me.
