Product review (5 stars): The first one was doing a good job but
This is our second one. The first one was doing a good job but, after a week, it started only  making 3 ice cubes at a time. We decided to return it for a replacement (same ice maker). Amzons return process was top notch and seamless. They couldn't have made it easier. The second machine we received was delivered upside down (we all know how refrigerant dislikes this). We let the ice maker sit (right side up) 5 times the recommend 30 minutes. When we first plugged it in, it started making ice as expected (comparing it to the first one). However, after every cycle of dumping ice, we would receive a " low water " alarm even though there was plenty of water in the reservoir. We wouldn't add water, just restart it. It would then complete another cycle, dump ice and then give us another "low water" alarm. Every once in a while we would add just enough water to maintain the optimal  operating level. This went on for about 10 cycles and we were getting discouraged and was considering again to return the product. I don't know what happened or changed (air trapped in the system from the way it was transported?) but the little machine decided to show up and show us how it can make ice. It's amazing ... makes 9 large ice cubes in 9 minutes! The "low water" alarm issue has disappeared. If you keep the water level within the prescribed limits, this little rascal will make and dump ice 24/7, every 9 minutes. If the ice bin gets full, of course the machine will turn off the ice making process. But, dump the ice and wait a minute it auto starts and you have ice ... in 9 minutes ... if the water gets low, you will have to add water and restart it. All in all, we are very happy, happy, happy.
