Anyone use TPMS (TireMinder type system)?

I would have a TPMS for any tire rolling on the road. My TPMS has saved me from near disaster several times. The cause for most blowouts is driving on low inflated tires. You might sense a low tire on your main rig, but probably not on a toad.

Most recently my TPMS warned me of a tire getting low while I was on the interstate. I was able to get off the road quickly. My tire was down to 8 lb. Turns out I picked up a screw.

I didnt know aftermarket systems were available, Id consider getting a trailer set up. My 05 4runner has it, it currently has a bad sensor in the spare I believe, and reminds me to check it if it stays on full time. When its at full pressure it flashes, when it gets low it stays on. I think its a good idea for the most part and when they work right. Mines at 250k and seems good other than a one sensor. I understand they dont cost much to replace if need be, under $20?
