Measure greater than 5 psi. And that is generosity. The display is well lit and easy to read. The on/off buttons for the display and the device itself are a good option. In general, the design of the American device seems solid, except for the fixed cartridge. The price is decent compared to other devices of the same style. If the accuracy was +/- 1 psi I would give 4 to 5 stars.
