I've had a long set of issues with FoboTire since I installed the system a while back. It sets off alarms all the time, even when there are no low pressure problems. Seems the in-car control until can't read the senders on the tires and thus sets off an alarm. It's a real PIA with the alarm going off all the time for nothing. Today I was exploring buying a new FoboTire set but then found what appears to be a very good and less expensive alternative: Accutire. It's not yet being delivered but starts shipping June 15. It has no in-car unit -- the tire valve caps communicate directly with the iPhone or Anroid app. Mine will be delivered on June 17 so I'll try it out and report back soon. Acutire is available on Amazon for $82.00, which is far less that the Fobo system.
