Assembly is easy enough using the instructions, following drawings, no text. Holes in the stainless steel hopper sides match exactly with the installed rivnuts. The tiny bolts are easy to drop and lose, so pay attention, but all goes together nicely. The unit fits over a 5 gallon plastic pail, but with the hand crank, it moves around a lot, and would benefit from being bolted to a stand, I suppose. I found that it worked fine over the bucket when powered by a cordless 1/2" drill. Apples cut in half work best, but whole apples up to about 3" ground up nicely too. The cutter teeth are of a delrin looking material and held up with no issues processing about 30 gallons of ground apples. Overall this worked well for apples ground for the press. Included is a notched wood brace to stabilize the hopper sides by snapping over the sides on top. If using a motor, some type of cover or lid will keep the bits from flying.
