A well made substantial air lift jack, only criticism is that it does not come with a Schrader Valve to 1/4" NPT (M) valve, bearing in mind if this is for use when out and about, you probably won't have an compressor in the back of your vehicle, so would have to use an air inflator, and as most come with a Schrader Valve clip on connector, would have though a Schrader Valve would be included, every other copnnector is.
