I have two (see the first vid a couple of posts back).

I had a few issues with the first one - all down to my lack of experience and knowledge, and a not-so-good set-up. Brett helped me enormously, and with his advice and feedback, I got it all sorted and she starts first pop every time now.

My second JJ-3000 arrived just on Xmas. I set it up using the knowledge I'd gained from my first Turbine, and it started first time out of the box, and went straight to idle. Smooth as silk and no issues whatsoever

Hope this helps...
