I read the negative reviews and still purchased. Used twice (about 10 pounds of ice total) so far and it crushes as I expected and desired. Did not want snow-cone shaved ice as there other units that do that, just small crushed ice for drinks. Understanding it is not a commercial unit, I did not feed it large "cubes" or chunks of ice - just smaller pieces.  It handles the load well. I was pleasantly surprised.

Just don't expect a commercial-grade crusher. It is a lighter duty home unit.

UPDATE - I have used it more than a dozen times and more than 50 pounds of ice.  Still works like the first time.  Still don't feed it big pieces. Occasionally a couple of pieces are frozen together, and if they are too big they won't go down the chute. But average cubes are no problem.
