This thing works great and has loads of leverage for M12 and 3/8" Rivet Nuts, but I think the seller's tape measure is a few inches too generous. I was curious because there are so many very similar tools on Amazon, and this is the only one that said it was a full 17" long. Sure enough, the arms measure in a hair shorter than 13" and tip to tip it is only a hair longer than 15". Giving the seller the benefit of the doubt, I kept measuring. Sure enough, if you put the M5 insert into it and spread the arms all the way apart, then from the tip of one handle to the tip of the other handle, it is almost exactly 17" (it has to be the M5 though, because the different inserts are sized to limit the stroke so that it is a bit harder to break - any other insert and this would be shorter or longer than 17").
I have not had any problems with broken parts yet, but I can totally see how there is enough leverage in the handles that you could snap some of the smaller insert bits. I would highly recommend testing the thing on a loose rivet nut first to get an idea of how far and how hard you need to pull before you start breaking things.
This is also my experience with rivet nuts, and if you are thinking about giving them a try, they are a very slick way of fastening things to thin metal.
When I went to put it away, I did find myself wishing I had spent a few extra dollars and just gotten a "shorter" one that came with a case.
