I gave tc a several day trial... I saw the benefits and the downside... for me and my style, killing my battery faster, means I don't use it. I might not have the most perfect and prettiest coils, but they are functional and my wicking works... so I don't get dry hits with the two tanks I still use, the rest of the time I squonk... I can do a full 5-8s puff and not get too hot even 28.5w on the tanks, unless I'm road raging.. but that's another story. using the tc is great if you like it and can be ignored if you don't. when I get a dual bat mod i'll rethink it since I've switched more to SS over kanthal.
