Review on Accurate and Convenient: Introducing the Topeak Smart Head Digital Air Pressure Gauge by Brian Weese

I stumbled across this digital meter while looking for a replacement for my cheap + broken digital meter. Pros: + Very easy to use, nice shape, feels good in the hand. + Long-life 3V lithium battery. I have never had to replace the gauge in my meter and have had it for many years. + Automatic shutdown. + Beeps when the gauge is ready and the pressure is still displayed. + Measures up to 250 pounds per square inch. .+ Smarthead can be configured for Presta or Schrader valves.+ Readings in psi, bar or kg/cm². Cons: - Not the cheapest digital air gauge - This gauge can be hard to find as the new version has replaced this one - The power has to be cycled to reset the gauge for the next reading. A bit uncomfortable, but you quickly get used to the process. - Pressing the power button too hard will destroy the inner stop. This was done with my pressure gauge, which required me opening it up and using superglue to fix the broken plastic piece.
