Any body used the MCLS multi joint box joint jig ?

[dennis thompson]

I have had no success making a box joint jig, too tight, too loose, etc. I'm looking at the MCLS multi joint spacing system. It allows you to make 1/4", 3/8" and 1/2" box joints on a router table. It's only $50.
Has anyone used this ? How did you like it ?
Thanks

I haven't used it, but I've made jigs just like it. Mine also gave bad results until I figured out the MCLS router bit was undersized. They actually refused to give me a refund as 0.24" was really close to 0.25".
