Honestly I wouldn't be too worried about it. If you wrap a good coil and test it with a multi-meter you should be fine. Use a protected battery if it will fit.
Excited about my mini coming..
Just don't lose it. It really is a mini. I love mine.
Long thread - covered most but can't find answer:
Can you stand it on end without firing it? Hate to have atty leak, and don't want
to have to adjust button every time I set it down. Sabe?
Thanks for the answers about standing it on end. I also hope that doesn't mean it is hard to
fire it with a pinky. I'm gonna get one in a coupla weeks, anyway.
It's very easy to fire with the pinkie, and I have arthritis in my hands.
