Adair Track Tuners

[gunner22a]

I've read a lot about them and for the $400 that they cost they seem to be a wise investment if you are running rubber tracks. So far all I hear are good things. I'm getting ready to order a set from them because there are no dealers handeling them here in Canada that I can find. Before I do I was wondering if there was anyone out there that had a bad experience with them or has any negative comments?

Thanks in advance for any input that you have.
