Description of Performance Tool W9107 Digital Pressure
Backlit display and convenient lighted tip. Triple function display P.S.I. BAR, and KPa. Auto off feature: Automatically shuts off in 30 seconds when not in use. Accurate to +/- 1 PSI. Requires (5) AG13 button cell batteries (included).
Based on my observations this tire pressure gauge is a great addition to my garage .It is very accurate and provides a clear read-out, allowing me to easily determine the pressure of my tires. The ergonomic design also makes it comfortable to use. However, it requires a lithium battery, which may need regular replacement..
Works as advertised. The only criticism is that the screw in the battery compartment is very tight and I don't have enough arm strength to open it to change the battery. Must ask someone to try. Otherwise does the job.
