Product review (4 stars): Here's how it works...
We bought a Danby ice maker (model DIM2500WDB) at Nebraska Furniture for around $150.  I hated to buy one without reading some reviews but hubby insisted, it was first one wed run across.  It's big, half the size of a large microwave.  Its noisy when it's making ice, hums and beeps a lot.  The operation instructions leave a lot to guess work, but its fairly simple.  It has 3 sizes of ice but theres not a lot of difference in sizes.  The ice is a bit on the soft side which I like, it gets crunchy.  It takes about an hour to get a basketful of ice, but you can scoop out what you need as it makes.  The unit does not have any kind of refrigeration/freezer to keep ice from melting, so unused ice in the basket gradually melts if you don't use it, and reuses the water to make more ice.  That seems to work well.  In spite of this, the ice lasts quite a while in the basket.  I like the machine and its worked well.  My main complaint is the noise.  But once it has a basketful it will beep 8 times and cease operation until you take out the ice, add more water, or it has enough melted water to make more.  On the whole, Ive enjoyed it.  It's worked well for several months.
