189 dollars to give me a read out of my tire pressure. That's really about all it is, pressure deviation is a joke since it will jump up and down normally.
Heat ? it's 105 I am doing 80 I expect the tire to be hot. The tire starts to loose air on a car you may not feel it at first, on a bike (scooter) you will know it just as fast as your gage.
And I think I would know if I had a flat without reading the gage. :?
But yes it is interesting....

I guess there are times it may help, if you want to take your eyes off the road to hit buttons.
