Product review (4 stars): Does the job
I have waited a bit to write the review as I thought it would be better to have info on how it works ~ I am an ice cruncher and purchased this machine so I could have ice cubes that I could crunch.  First tip is you have to let the machine sit for a day after shipping before you can use it.  Basically, the machine does its job and makes ice.  As noted it is not refrigerated so the ice in the bin slightly melts.  What the machine does is run the water from a reservoir in the bottom up to the top where there is a little tray that opens and closes as the machine makes 12 ice cubes in about 10 minutes.  The cubes fall into a bin which holds about  of a gallon Ziploc bag. If you wait too long to remove the ice the cubes on the bottom will start to melt, so it can tend to be a wet mess.  There are fill lines in the reservoir but since the machine sucks up water it can be easy to over fill it.  I was cleaning the machine and using a flashlight up into the guts I found icky mold way up in there.  This lead to a thorough cleaning during which I tipped the machine on its back, etc., to get a visual in the nooks and crannies.  Since I did that I decided to let the machine sit for 24 hours before turning it back on.  When I turned it on it made horrific unstoppable beeps and none of the buttons would work.  I kept turning it off and on, unplugging it, etc., and finally it snapped out of it and started to work.  Since I used bleach to clean I ran an entire reservoir through and tossed out the ice.  After that it tasted okay, and the machine is back to working great. I have been draining it and wiping it down and not leaving water sitting for any length of time in the reservoir, but it  is too soon to tell if that alone will resolve the mold problem.
