Product review (5 stars): Only portable ice maker that doesn't make slush
I've been through several different ice makers and most of the other ones that cost ~$200 (i.e. Kitchenaid, Edgestar, Haier, etc.) produce ice that is barely frozen.  Think slush.  What this means in practice is that if you fill a glass to the brim with ice from those cheaper models and pour in tap water, the ice will be completely melted in about 10-15 minutes.  In other words, unless you are drinking water or intending to water down your beverage, these ice cubes don't do the job adequately.  Enter the Waring Pro WIM30.  The reason they advertise "Clear-Ice" is because the ice that comes out of this product is actually solid ice.  This ice lasts much longer than the slushy ice, about as long as ice cubes you would make in a tray in your freezer.  (slighly smaller cubes and more surface area on each cube since they've got a hole going through them, so not quite as long)  The price on this unit is about twice that of the cheaper models, so it's a steep price.  However, because of the watered-down (alcoholic) beverages I managed to produce with the cheaper ice makers, those products were not actually usable for me, so their cheaper price is irrelevent.
