I have used this gauge on maybe 8 different bikes and a few vehicles. I keep it in the glovebox. The tricky thing is that the presta cores that have a large wrench flat (ex: OEM Mavic on the 819 line, etc)tend to get caught before bottoming out the adapter bushing/rubber and causing a leak/impossible read/frustrating experience. I thought at first the unit was defective so I contacted Planet Bike. They sent me another unit that had the same issue (for me anyway). The service provided by Planet Bike and Jenson USA were was top shelf however owning a few tubeless Mavic set up bikes, I have to drop the rating. I can use the p/s adapter or a presta extender to overcome this minor issue however it seems like the next iteration of the tool could easily address this. I did give one of these away to a friend and he has been pleased also.

PROS: Stable, Precise, Rugged

BEST USES: Road Bikes, Not Just Bikes, Mountain Bikes

bought this after 2 attempts at using a digital gauge. This is simpler and more robust. The price is great too.

PROS: Rugged, Precise

BEST USES: Road Bikes, Keep In the Garage, Mountain Bikes

Works well with presta or shrader. Holds the needle at the measured pressure, so you can comfortably bring it up and see the precise pressure. Click the little button to reset the gauge.

Good solid feel. Precise readings. Too heavy to take along but excellent for the shop.

PROS: Precise

this gauge was not good, it does not fit presta valves on tubeless MTB set ups. I tried to use on other presta, it fits but the gauge is consisently about 8-10 psi off when compared to other gauges and also used my car tire as a standard. steer clear of this product

CONS: Inaccurate Dial, Tube Too Short
