Dear esmokers, I'm happy to be here with you. I'm beginner, bought e-pipe couple days ago and smoking for about three days. I have DSE 601. I tried several models, including penstyle and super mini, but this would be simply the best if it weren't for one thing - about 70% puffs are OK, but the rest tastes "plastic". I tried several cartridges and always the same effect. I think it is caused by fibres from the cartridge, but the atomizer is clean. I'm afraid it's natural, because the cartridge "lays" on the atomizer. Do anybody has the same experience, or do you think it has some other cause? Thank you very much for your replies.
