Product review (3 stars): Overall works well; two kinks
I have never had another ice maker so I am reviewing this in absolute rather than relative terms.

The first one I got worked fine for a few days, after which is started making a very annoying sound while it was generating ice (I woke up to it in the middle of the night). I returned it and got a replacement. The new one has not had the exact same problem, but every now and then there are short bursts of this same sound. So, I suspect there is a tendency there.

The other problem is that it often will make too much ice, to the point that I've seen the mechanical ice shuffling "arm" not have freedom of movement. I am not entirely sure why; the best hypothesis I have is that the weight sensor (assuming that is what it uses) gets thrown off sometimes when the ice is slightly melted and the ice cubes stick to each other. Perhaps when this happens the full weight isn't felt, because ice cubes on top are getting some support from surrounding areas outside of the ice tray.

The combination of these two has made me not keep it turned on 24/7, which is a shame because it means more micro-management and I don't have fresh ice in the morning.
