I think I am the only one that has this opinion, but I hate that it uses a insulator out of a joytech product, and if you want more you have to buy the heads to get them, they are too soft. I destroyed one of them by just installing the tank 6 times. I only ever got one coil to fire, then the insulator ripped, I have dug it out a few times and tried it again, but each time it has failed. The thing is everybody else seems to love them, and works great for them.

Maybe I will try again this weekend.
