My experience with ego is not good - I first got a T, which was finicky to say the least - I tried silicone caps, different atomizers, filling different amounts, right side up / upside down etc. I got sick of burnt plasticky hits and leaks at the other extreme. Used Boge LR cartos which were much better, tried a liquinator tank that vapes awesome but is a major pain to refill. Heard that the ego C had fixed all the problems and like a fool bought one! If possible it is even worse - right from the pack - every tank leaks. Same plasticky hits going on as well. I will say that they are very well made, and the ease at taking apart the atty is great (and you’re going to need that feature...) - they just suffer from an inherently bad design. The batteries are excellent so I don’t feel like I wasted all my money - plus they fit all sorts of other stuff. I have only ever used Halo juice in them (which is fantastic - highly recommend it). I got into vaping to give up smoking, not start tinkering with stuff that just isn’t ready for prime time - I wish I could find something that JUST WORKS, but the ego T/C isn’t it for me :-(
