TPMS and no warning tire failures

[Blackhat6mike]

Just climbing into the TV each morning, turning on the TST system and getting a reading and not having to physically check each tire, is well worth the price of the unit IMHO.
I periodically unscrew each sensor just to "flex it" and make sure it is working OK. I have yet to have any problems with this monitoring system. Don't know anything about any of the other systems other than the negative post here on the forum.
I just replaced all 4 batteries before making this 550 mile trip to the FL Keys. All were still working, but its preventive maintenance. Four batts = cheap assurance things will go well.
I'm a retired commercial pilot and don't like it when things break unexpectedly. I've had so many problems with tires in the past that I feel like I can't do enough to make sure all is well up front.
