I have 2 say I love the regular eGo setup with 510 atty and cart, but this new tank cart is sooo smoothe and has a nice draw, just got it an hour ago in the mail, so full flavor is not quite in full effect yet. I'm still tasting the primer they put on the new attys, but with every puff it gets better and better! Great vapor production, bellows of vapor, atty seems nice and strong, working properly. No burnt polyfil taste which is what I was anticipating. Finally something new that is a major breakthrough in vaping! I'll report back with an update when all is broken in and trying diff flavors, my regular use juice is a menthol blend "COOL MINT" as I'm a menthol guy. Any questions hmu!
