I bought a whole kit a while ago, with tool and nutserts. Have only used it a couple of time and found when pulling up the nutsert using the tool I have stripped the thread inside the nutsert. I think I haven't had the tool set right for the thickness of the paneling, but the kit came with instructions that are pretty much useless. So as of late I have just done it by feel with success.

Very handy item to have though.
