My last couple posts have been me raving about the thing. It's my newest device since my Buzz Pro 2 years ago, and I love it. There's a whole thread here where people are talking about it. Personally, I think it's great, and I went with the Lemo to go with it for my first RTA since the istick can tell me the atomizer resistance, and I've been having a lot of fun rebuilding and enjoying new flavor from my juices. Give it a shot, it's very inexpensive.
