Very easy to set up, read and understand. I use this system for my 25ft RV and it works great. I would recommend TPMS to anyone towing a trailer for safety. My only criticism is that the wheels need to be in motion to give pressure readings. So if your tires are flat BEFORE you hit the road, you won't notice it until you start driving. Not a huge deal breaker but don't expect to know the pressures before you move. It would also be nice to know what temperature limits should be set for alarms. That was just a big guess on me and I originally set it too high, 170F. I'm in Southeast Texas which is very hot right now, but I'll set it at 120F or so.
