tire pressure monitoring

I posted this elswhere but may be more appropriate here. I've narrowed the list to Pressure Pro and Tire Safe Guard. Pressure Pro a little less $ but Tire Safe Guard monitors temp as well and air can be added with out removing the sensor. Any experiences would be appreciated. thanks ric
Re: tire pressure monitoring

I saw your posts here and "elsewhere" and didn't see any replies about Tire Safe Guard. It's been a year since you were inquiring. Did you ever find any feedback on this system? Did you wind up buying a system. If so, which one and how has it worked out? -- Kathy
