I have the TST system with removable batteries and am not totally pleased with it. First it wouldn't always pick up the sensors on my 38' 5ver so I had to put on the repeater, seamed to work OK for awhile after I did that. Then last year it couldn't really be trusted at all. Some of the tires would not change pressure or temp for 1/2 hour or so at a time, tire could have fallen off for all I know. I never really cared for their display either, Oh and I changed the batteries every spring.
So what other brands are out their that are good?
