Not tested...missing funnel.. At least I think it was supposed to include a funnel... Box is surprisingly okay for its age.Normal signs of wear.. Tape on the bottom subtle tears and rough edges... Please look at the photos closely for condition.You can clearly see the glue marks everywhere... You are obviously taking a risk that it doesn't work... From what i've read it can work periodically, probably based on a simple pump system... Is where if it's sucking air at any point in time , it will not work... Please see photos for condition... please ask questions prior to buying... If you need additional photos please ask prior to buying...shipping is based on location
