Have had Pressure Pros on for more than ten years. Have replaced all of the senders by this point - the batts last about 8 years.
Started out with 8, went to 10 with the new truck and then 14 with the large fiver so my sender ages were staggered.
I have an antenna under the rear of the truck that is hard wired to the dash readout in order to get reliable signals from the trailer tires.
Been very happy with the system. Best feature is ability to scroll through the pressures every time I climb in the truck - especially nice on a cold, rainy morning!
