They are one time use. Pull them to remove a spark plug and the connection at the plug tears out of the coil. Ruined over 10 of them this way only the have them tell me they've never had that problem before and I was doing something wrong. I only know of one way to install and remove a coil.

I had the EXACT same problem! They acted like they had no clue how it happened! I sent them pictures and everything! Now MSD has come out with their coils also. I've had the granatelli's for over a year now and have never dyno'd the car so can't say if it makes a difference or not.
Yeah they had a lifetime warranty. But the Tommy Boy quote applies here. "All you bought was a guaranteed piece of ...... But every time without fail they would strip apart when I would check plugs. The last time I removed them 7 of 8 coils self destructed.
It's so irritating dealing with companies like that. Simply admit there's a problem. It's not the end of the world. Treating people like they're idiots and blaming them for their products short comings is not how you do business.
