Worked for me too. We only have them on one car, the light activated right during a quick drop in temperature, and the tires looked normal, so I thought it was false alarm. I checked, and one was a little low. Next AM, it was definitely low, and I found a nail in it.
It would be interesting if there was any actual cost/benefit analysis, and if other changes would have a better bang/$.
