Product review (4 stars): Not as efficient as a chest freezer, but ...
This freezer does the job reasonably well - it doesn't get things down to 0 degrees farenheit, but it gets close and that's good enough for my purposes.  Things are very safely frozen in this thing.  It also isn't very noisy, though you can tell when the compressor kick in.

One thing to note is that the shelves are not removable (without disconnecting the "quick freeze" mechanism, which I'm not sure you can and which I don't think they'd recommend) or adjustable.

Also, keep in mind this is not a freezer for storing items you want to get to regularly (e.g. don't put ice pops in there on a hot summer day and go running in to retrieve one every few minutes).  This is a freezer designed for storing food, not regularly accessing it.  It will frost over quickly if you open and close the door a lot and defrosting it means emptying it and letting the ice melt and cleaning up the water.  It doesn't have a drain.

I would have preferred a chest freezer since it would have been less expensive, easier to defrost, and more efficient, but I needed something for a space that wouldn't allow me to have an open top and this Danby does the trick.  If you can fit a chest freezer in your space and don't have a reason for needing an upright, then get one, but if a chest freezer isn't an option, this is a great choice.

All-in-all, I'm very happy with this freezer.  I could have paid a lot more and gotten a better freezer, but this suited my needs.
