I haven't tried them, but from what I read they are awesome.

their the only thing I'll put on my hunt'n arrows

I DO,I DO..................

Me too.

qzq38b do they clearyour QAD rest?

Yeah...and do they fit snug? Do they slide forward (towards the broadhead)?

Yep - I have no problems with my QAD rest using FOBs - anymore. At first I didn't have the rest set up right and I had contact. But I've got it dialed in now. The key was using the TL1 launcher and getting the cord length just right.

As far as sliding forward - the design of the FOB makes it impossible to slide forward toward the broadhead. I've got no complaints. Customer service is great too.
