I was using CE4 for 10 days now and today I got pretty nasty taste out of it but I guess its use period just ended. I vape about 2ml of ejuice per day but I chain vape when I'm home so I guess 10 days is not such a bad result for CE4's. Or maybe it is? I wouldn't know

I will try cleaning it with water and dry burning it right now.
So far I've heard only good things about iClear 30s so I guess i will give it a try tomorrow.
Do you happen to know how long can I use iClear before having to change it completely or change the coil?
Anyway, appreciate your answer Deleon and Storm.
