Tried it - It was ok, kind of a crappy setup though (at least for my maxx, the cable to the rx is too short to work with the loop that goes around the head to take the temp, so theres nothing to secure it to inbetween)
I ended up just using it as a failsafe which it did do it's job and is fairly programable but it ended up getting jarred once and then started being flaky so I replaced it.
