Inexpensive is rare but so far this is one of them. So far I've used it on vehicles, trailers and bikes. Installs quickly onto Schrader valve stems without hissing or leaking. The blue LED display is easier to read than traditional pencil gauges. It doesn't hiss or leak, it's very convenient to inflate and deflate with one hand and only 1 tool. Too bad I bought this tool a few years ago.
