Killeen, I really like my Doran system. It took me a little while to get it all monitoring correctly, but just love the piece of mind that all my tires are being monitored.

I had to add the Remote Signal Booster and that solved most of my issues. It plugs into 110v, and I was able to put it under the bed.

I did have to have a number of wheel sensors replaced ( defective new sensors ) before all sensors would register, but I just called Doran and they sent me new units. NOW all 12 wheels are monitored and LIFE IS GOOD.

I would not turn the valve stems on the wheels, a sure way to get a leak. Wait till you need the tire serviced to have them properly orientated for valve sensors to be put on. Just my opinion.
