...does it exist? So far I've tried the eGo-T and Echo, and my experience has been very mixed. The cartomizers will start out great but after a day or two will deteriorate quite a bit in regards to vapor production. I've tried basic cleaning (soaking in water, flushing with a syringe) and my experience with this has also been mixed... sometimes a cleaning will restore vapor production quite a bit but sometimes not much at all. I'm not really interested in acquiring the tools for an advanced cleaning/rebuild, nor do I really want to have to fiddle around with cartomizers to keep them working. So, my question is, is there a product out there that can match the performance of a new eGo or Echo cartomizer, and can maintain that same performance with little or no maintenance?
