Looks like a typical junk tool, misspelled English letters on the box and all that. Works like a champ. Screw some teflon into the 1/4" NPT adapter, insert the siphon tube into the medium, connect to air and blow the air. Very wide nozzle orifice so it doesn't clog too easily and quite a wide spray pattern for a small blaster. 4 stars because the siphon hose is too short. Must buy to try sandblasting, don't forget the right PPE (protective equipment)!
