the only assembly required was the handle! I liked the quality of the unit, it seems well made, and was a heavier gage metal than I thought, which is a good thing! the only problem I see with all of the stuffers, not just this one, is where are the handles or handle to move the it with??? how about one on each side of the base, or one handle at the top, of course the gear shaft has to go up and down, and it would have to be a handle with a whole in it to allow for that. the 5 stuffing horns worked out real well, good diameter and length, and the churro disks is an added feature! there is no gasket on the nut to hold the tubes on, maybe for food safety reasons, and it comes with an extra main gasket, a real plus in my book. it seems heavy enough not to move with using it, and there are 4 rubber feet that fit real well on the base, or u can use the pre-drilled to bolt down to a counter. the manual does not have the address of the company, in California printed on it anywhere, but the package does. it is as follows:Hakka Brothers Corp. 1600 Worldwide Blvd. , Hebron, Kentucky 41048 or 23482 Foley St., Hayward, California. 94545 there is a exploded view of the different models in the manual, and parts numbers, but it doesn't give any address where to them from, and a warranty card but no address where to send it to either. designed in the usa, made in china ! there is also a bottle brush for cleaning, and it has an Air Vent on the plunger which unscrews for easy cleaning, and the cylinder tilts for easy reloading of meat and cleaning. the base is not solid, its hollow, but if it needs more weigh, that can be filled in with some S.S. welded in. The base is 12" wide x 9" deep and the unit is 20" tall. it is 2 speed and the handle can only go on the right side as shown in the photo. the horns have a 2" base. spray the shaft with food grade oil or food grade grease.
