TPMS system recommendation

I had nothing but problems with the tst system, now have tire minder and am very happy.

TST without a doubt. I had the Pressure pro and I could not justify the $250 to replace my sensors. Replaced the batteries once in 5 years, I remove my sensors every winter. I did purchase an additional TST for my car and will get another unit for my wife's car soon.

After 8 years I recently had to replace my Pressure Pro sensors ($25 each). Unit has worked well without a repeater and with experience you do not need one with temperature... to large an increase in pressure equals a big increase in temp. It's very nice to be able to check all your tire pressures sitting in the driver's seat before you pull out for the day and then several times a day. Pretty cheap insurance.
Buying new I would opt for ones that you can change the sensor batteries yourself.

Two of the biggest are tst systems and Eez. I bought Eez and have had it for about 10 months and 13000 miles. I did have to buy the repeater, but since then it has been great.
They are all made in China, and some are offered by different companies with the same unit.
Amazon sells several, but I bought from the Eez site, as it as cheaper.
