I am glad to hear that everything went smoothly with the install & the initial equipment check.

Side note/question - what psi does your TVs "doughnut" spare take? My wife's Beetle has one of those and I don't think I've ever even looked at it as it's buried deep in the cramped trunk. I am surprised that an Explorer has one of those instead of a full-size spare tire.
Amazon reviews are still holding at just 19 (there were 18 when I started this thread) so it appears that we are still in the infancy stage with this TPMS.
