Product review (1 stars): Can't recommend this one.  Not as advertised and unreliable.
I originally rated this unit 4 stars, but unfortunately after getting two units that broke immediately, I would change this to no stars if I could.  I bought this unit primarily to make crushed ice for tea and cocktails, and to make ice that fits easily into water bottles for biking and school use.  It worked well for that application when it worked at all.  The advertised settings for ice to make snowcones and slushies are non existent, which was a disappointment.  It makes chunks of ice about 1/2 inch big, a few larger and a few smaller.  The feet of the machine are little vacuum suckers, so the machine does not slide around during use.  UPDATE:  Unit worked fine with a minimum of jamming for about 10 days, and then the blades stopped turning.  As per instructions, I let it sit to see if there was a piece of ice stuck, but to no avail.  The motor buzzed, but nothing was moving in there.  I returned it to Amazon for an exchange.  I'll give it a second try, but if this unit fails, then I'll return it for a refund and try the Waring also listed on this site.  UPDATE 2:  The replacement arrived, and lasted through one tray of ice cubes.  Again, the unit is jammed for no visible reason.  Back it goes, and for a refund this time.  Not recommended.
