Read my comments on them in that same thread.

They are made out of cheap hardware store junk, and I've been stuck without 4wd working twice because of the cheap clamps allowing the cable to slip.
The don't respond to complaints (I've e-mailed them and they haven't respondeed), and I know that they haven't tried fixxing the problems. (they might have to spend another $2.00 to make a better kit)
If they were better quality they would eliminate all your vaccum related 4wd wow's. Nothing that wasn't vaccom related.
I'm thinking of trying to design my own version using a power door lock actuator instead of a cable.
If this system works you could even wire it into your 4wd switch and make it fully automatic.
I won't be able to work on this design for at least 2 weeks, but IF I come up with something that works reliably I'll post it as free public information.
I'm thinking that it'll cost next to nothing to make this setup with autowreck parts.
