Your experience with the caliper is the example I used to give people for why they need a TPMS. Thank goodness you had one! Nice to hear that it helped.
But the issue we're concerned about is this:

It didn't take long to see a dropped sensor here and there.
When you SEE a dropped sensor, it's signal has actually been lost for the past hour.
By the time you hear the alert beep and the reading on the monitor for that sensor goes blank, your monitor has been "frantically searching*" for your sensor's lost signal for an hour.
You don't see or get any alert that the signal has actually been lost for an hour.
You still have a reading on your monitor for the lost sensor. But that tire pressure and temperature shown is from the last reading received...which could be an hour ago.
Alot can happen in an hour. Imagine if your caliper had had an hour more to heat up and you didn't know your sensor's signal was lost because your monitor was still giving you readings from memory.
Until recently, I didn't know that.
When you hear the beep alert and the reading blanks out, it means your monitor has given up trying to locate the sensor's signal "after an hour of trying*".
I'm really glad that your system worked well for you when you needed it, Di. It could have been so much worse! And it's great that you and Dutch have added a repeater/booster. We added one, too.
I wonder how many people out there don't even realize that they need one, ya know?
