I'm one of the ones who was also disappointed with the eGO-T. One of the 4 atties I purchased popped a week after arrival. It was replaced free, and I was happy. I also got the burned taste on several oocasions, and fixed it by dripping on the wick. However, the biggest problem I had with the eGO-T was the taste. There was a musty, plastic taste...like water that's been left in a cheapo plastic bottle in a hot car for a few days (or longer). If they made the tanks out of a decent, food-grade plastic, or even stainless steel, then the unit might work. Since that hasn't happened (that I'm aware of) then I'm back to carts & atties and cartos. Too bad, as I like the size of the eGO, and my batteries work like champs...even though they're the old style. Concept good, execution bad.
