Product review (5 stars): I am an addict and do not want to live without oneof these icemakers!
I've owned approximately 5 of this type of ice maker, and the average longevity has been about a year, but I cannot do without one.  I've tried to give up on them and actually get depressed.  I have grown to accept the fact that these ice makers don't last as long as I would like them to last, but I love them too much to be without one.  There is no mechanism within the ice maker to keep ice frozen, so I find that the faster I transfer the ice into a zip-lock bag and into the freezer, the better.  The ice tends to melt into clumps that easily break apart when hit with a wooden lemon juicer.  I love ice, so I use it for a couple of hours every other day or so.  I'm always surprised how fast the ice is made.  Mine have all had two sizes of ice, but there is not a lot of difference in the sizes.  I'm so happy with this product that I have resolved to live with any shortcomings.

P.S.  In rethinking this, I think my ice makers have lasted about two years.
I have noticed that many of my electric appliances last longer than other peoples.  I believe this is because I always use filtered water in my appliances.  If filtered water is not used, calcium quickly builds up and clogs and jams parts.
