Yep, I love it. And it seems to be on the money. I fill the tires and get the fronts to match and the rears to match and 98% of the time the display has them matching exactly. As they warm up, one may register the increase sooner than another, but they all eventually match. So I'm able to tell if one tire has a slow leak compared to the others. The system in my wife's outback is similar, but reacts more slowly.
