Now my 510 T was ok but the attys would go bad after a few weeks and thats just no good. So I found a guy who was selling Ego T's at $36 for a starter kit which was the best price I found anywhere. I've had it for a few days and I love it. Great vapor production and I like the manual over auto batts now. I've also ordered a few different cardos to try, some Boge, and a few duel coil carts to.
