I bought my first Ego-T tank system in January, and both atomizers are still going strong. I do change my tank weekly when I clean the current atomizer. I figure it is cheap insurance against leakage, and a fresh tank will be a custom pierced fit for the second rotated atty. I only clean by soaking in near boiling water for 10-15 minutes, shake out excess water, and dry overnight. I rotate my two atties weekly after cleaning. When practical, I often rinse my tank between refills, blowing out the excess water. If I use straight Pg, I will sometines notice a small drop of leakage on top of the battery post when taken apart, but when I use my normal 70/30 or 95/35 mix, very very little to no moisture. I take long slow puffs, and will puff a newly filled tank a few times without pushing the button to prime. I vape 3 to 5ml daily with excellent vapor, good flavor and th. I think the important point is I don't tinker with anything including wicks, chads, etc. I use the tank system as it was meant to be used, straight stock. After reading of problem after problem, I thought I would post my methods and experience in the hope it might be helpful and useful to some of those with problems.
