Negative Positive
Title: Looks fancy, but has no value on the track.
Review: This gauge makes one (probably very precise) measuring. The problem is that the display does not follow the current pressure after the initial reading.When bleeding excess air from the tires to reach a certain pressure you make a reading, let some air out, remove the gauge, empty the trapped air from the gauge, attach the gauge again, make a new reading, let some more air out, remove the gauge again, release the trapped air, attach it again, make another reading .... the device looks cool, but has no real value.I'd recommend getting a good quality mechanical gauge instead.
