I initiated a return immediately after getting it.  It leaked oil and would not pump.  Terrible paint job all over and the relief valve was painted into position.  Obviously poor quality.  Thank God for Amazon returns.  It is all packed up and will mail it back tomorrow.  Looked for a higher quality bottle jack by reading the reviews on the site, seems they are all badly made.  So ordered a Craftsman, and will see.  Why isn't there a quality bottle jack at a reasonable price?
