I've used Pressure Pro for about 3 years now and loved it. But I REALLY love it now since I took advantage last June of upgrading my VMS320 (I know I should upgrade it too.....) to have my existing Pressure Pro sensors display on the 320 and took out the PP display and put it in the tow car for use there. I use the display on the 320 MUCH more than I did the PP display because on the initial drive display it cycles through each tire automatically and shows it's pressure without having to press any buttons. I wish the software upgrade and transmitter were available before I bought the PP display... it would have close to a push in cost...
