Kind of an old thread, but I just got a Zmax Mini from (I guess I can't say. LOL), and I'm so excited! I told the person I got it from I kinda expected it to be thin and tinny, like my Mini Lambo (which is like paper thin stainless, but I still like it). This Sigelei is so solid! I have one with the slant top, a metal button (or chromed plastic? Can't tell), and the extension tube and other end cap for the other battery sizes. This thing feels great, and I love the little screen....I really wanted something with a little screen!
My first purchase after quitting smoking using cigalikes was an iTaste 134 Mini, and I got 2 18500 batteries and 2 18350's to go with it, and just never bothered with the 18350's in it, cuz they don't last long. I was really just looking for an excuse to buy something new to put those 18350 batteries in. I'm so happy I got this new toy! And it wasn't expensive, so I have something new and shiny to play with for a while and I won't starve.
Hmmm....maybe I'll get me a couple huge batteries now that I have something with extensions....
