I've had the FOBO on my 09 Wing for about a year. It is a great product and always reads within 1/2 lb. of psi according to my digital pressure gauge. Only issue I've had, (and haven't been able to resolve), is that I got a new phone and now can't get the sensors to sync. I'm sure it's likely my lack of tech skills that is the problem. But, it was a breeze to set-up originally!
I've had problems with my FOBO's almost from day one. They don't operate consistently. I bought two sets. (for bike and trailer) When one quit working I bought a fifth FOBO. Soon that quit working too. Not the batteries. I've tried new batteries more than once. As a test, I've installed a set on a different trailer and they worked, moved them back to the bike neither worked again.
I've had these on my 08 for 18 months and am glad I have them. But:
1. Do not install the sensors on rubber bent valve stems. Trust me! They can cause the valve stem to break at the rim hole.
2. Buy the metal valve stems they sell as an extra. Well worth it since my rubber stem broke during a spirited ride returning from Vermont on my way home to NY. The alert came on as my valve stem failed.
3. Their customer service is excellent. I changed my cell and had to reboot but didn't know how. Sent an email and promptly received a reply. Problem solved!
Thanks for the comments! Great feedback.
Isn't TPMS standard on newer Wings?
