tire pressure monitor systems

I couldn't find much with a thread search but was wondering about how the systems that go inside the wheel compare to the valve stem cap type. And would also like to hear everybody's experience with these systems.

My 2012 Ram has those and so far they have not been a problem. I can take'em or leave'em. I did have a huge bolt go through on of my tires and it told me which one, but it also didn't take long to figure out which one of them went flat either. It kind'a pulled to one side. It is fun to play with and watch the pressure change during the day, but that's about it. There has been no problem when I go to change tires either.

I used to have one on my MH (before stem type came out) and it worked great. The company who I can't think of the name pulled out of the RV market. I had problems with getting the tire changed on my tow rig as the people didn't know how to do it. MH tires no problem.
Think they are only good for 18 wheelers as they change tires regular and replacement of batteries can be done on regular maintenance.
With the stem type available I guess that why they pulled out of the market.
The cost was like 2-3 times the stem type.
