Product review (4 stars): It's fast, but it's smallish cubes and they are wet, so transferring to the freezer means they freeze together in a clump.
This puts out the ice quickly, and is a real boon for holidays, etc, when there are extra people and the fridge's icemaker can't keep up.  I had 14 people in the house for a week at Christmas.  We live in a tropical climate, and this thing saved us!

I have 2 minor complaints.
1) The ice isn't frozen real hard, and the exterior is wet.  So, when I dump it in my freezer's ice tray, it all clumps together.  Granted, I live in Key West, but even with the AC on I have this problem.
2) I find the drain plug in the bottom a little hard to get out.  It simply pulls out, rather than screwing out.  Since it's in a small, recessed area, it's tough to get your fingers in there to pull it out.
