I was thinking about getting a set of Fireflys (valve stem pressure sensors). The guy at the motorcycle shop said that they work great, but if you do a lot of high speed riding they could damage your valve stems due to the weight of the Fireflys. He didn't qualify what constituted "high speed" riding.
I was wondering if any of you are running with Fireflys and how they have worked out for you,
Thanks

I think you will find the general consensus is they are junk.

I don't think most of those kinds of things are very accurate. Personally, I wouldn't trust them, especially if there is a chance they can cause valve stem failure, which could be catastrophic.

Carry a good quality tire pressure gage and check before you ride, and during your ride stops if you feel the need.

Ride safe.
