Snap-on Warranty replacement

[Tynee]

It's never happened before, but this weekend I finally broke my first snap-on tool. Anybody know how hard it is to get them to replace something? I know I just need to get in touch with my local route guy, but I wanted to ask a key question on here, first:

Do you think that putting a cheater pipe on a 3/8" Breaker bar with a 15mm socket on it is abusing the tool?

I don't have a 1/2" drive 15mm, so my options were this, or a 1/2" x 3/8" adapter on my 1/2" breaker bar. I've broken enough of those adapters to want to go another way...
