Offering the compressor in a case means space for the Ring’s hose and wiring. Infla-tion from 20-30psi took only 90 seconds, and it was accurate at 20psi and only 1psi out at 30psi. But the gauge is fussy. The hinges and catches are cheap bent plastic and there is no light or auto cut-off – yet the blend of practicality, performance and price makes this our Recom­mended choice.
