I have looked at that one as well.  From my old truck driving days I remember that if a tire overheats they often blow.  It is a really good indicater that the pressure is low.  I used to just feel of my tires rather than hit them with the hammar.  If one was hotter than the rest than I would check it.

The one I'm looking at is quite a bit cheaper and evidently used by truckers.  Just trying to get some feed back on it. 

We were enroute home from Door County, Wi, a couple years ago when we blew out a set of duels.  I believe one had lost pressure and when it went took the other with it.  Twenty miles from nowhere. 

We sat and fixed lunch while waiting for a mobil tire changing truck to arrive.  I think that if I had known that a tire had gone down, I probably could have saved the whole deal.  Got a little spendy.  We were just lucky that we found one cause it was a holiday. 

Guess what?  The unit finally came today five weeks after I ordered it.  I had checked on the company and found many unhappy people who had ordered the unit and were waiting.  One clear voice had warned to be patient as their's had arrived after five weeks.  Seems the units are so popular that they are on back order. 

The unit itself is quite small and packed with software.  You can set pressure and tempature limits and it will automatically sound an alarm if they are exceeded.  The company also says they will replace any sensors lost or stolen. 

Well, have to get it unstalled and take a trip to see how well it works.
