Jon is Incomunicato but as his manslave he's asked me post this note about the LED tire gauge - be very careful.
He installed his right before our trip to OSH and one was blinging on arrival (left tag) and the tire was down about 10 lbs. He removed the LED and replaced the cap - no more leaking.
That night the other tag started blinking and by the morning was down about 20lbs. Since the device to read tire pressure activates the valve there is some seal within the device is leaking. If you add these to your tires please monitor closely.

PS Since Jon will be out digital contact at least until Wednesday night - feel free to take all those cheap shots while you can.
