I do not recommend it and am returning mine for three reasons. It requires minor reconfiguration to be used on Presta or Schrader valves. That requires moving two small parts inside the silver screw-on housing. For in-line pumping, I consistently lost a lot of pressure on Presta valves. It is quite large and barely works on a high spoke count touring bike.
This is a great product. You can attach your floor pump, or hand pump or your CO2 inflator head to get precise reading of your tire pressure.
I like the locking lever, make a very secure connection to your valve stem.
My old Joe Blow mountain pumps gauge stop working after less than a year. This gauge bridged That gap and gas station hoses. Great for when you want an accurate pressure when filling auto tires as well! Win win.
I use it when pumping tires. Attaching it to my tire pump gives me a more accurate reading than my tire pump.
Loved the idea of this gauge so I bought it based on the description of the manufacturer. Liked the digital aspect and ability to use it on shocks. However did not work as claimed on my front shock. Had to return it due to this issue.
