Product review (3 stars): Quick to make ice, but cannot hold it frozen.
I purchased the red Counter Top  icemaker by Curtis International, for $89.00.
Upon arrival, the documentation was ADAMANT about following the directions, placement, airflow, letting it rest for two hours before starting it up, etc etc.
So I followed the directions to the letter, and, I put the unit on the floor in the middle of my kitchen, so, plenty of airflow.
I have been careful to only use filtered water.  When I started it up, it made a reasonable amount of noise, not unduly loud.  when it is cycling, I can hear it in the next room well enough so that I could easily identify what the noise was, but less noisy than a standard dishwasher.
Makes small amounts of ice very quickly.  In one day, it makes enough to fill my 2 gallon ice therapy system unit.
But it requires continually removing the basket of ice and packaging it and putting it into the freezer.  The basket holds the amount of about two standard ice cube trays.  If you do not empty the basket, it will stop making more ice.  If the ice is not removed, but the machine is left on, the ice will quickly melt back into the reservoir and trigger making more ice, a significant power drain.
So it is not a unit one could just leave plugged in and on, whether one wanted more ice or not, as, the energy consumption would be significant, while not making any ADDITIONAL, merely replacement, ice.
As an auxiliary ice maker, it has been handy.  I have it to supply my two gallon (standard size) ice therapy machine.  It cannot really keep up with the demand of the ice therapy machine (for 24 hour use, it needs to be refilled with COLD ice 3 times a day), and because the basket is so small, one must empty the basket often (about twice an hour).  So, although it is fast to make the ice, the storage capacity is minimal.  I spend significant time servicing the machine.
 It is very heavy (condensers always are), so initial placement should be well considered, as, moving it is the same as moving one's microwave, not particularly easy.
I would give it five stars if it held its ice frozen, and if the reservoir were much larger.  Because one must be sure to turn it off to avoid the infinite looping of making and melting ice, and because it is heavy enough so it cannot be considered portable in the least,  nor will it hold more ice before automatically stopping ice making  it gets only three stars.
To get five stars, it should either have an automatic shutoff option or it should be able to keep the ice frozen, AND have a larger reservoir.
After five days of use, I have no other complaints.
If you have a need for quick ice making and you can live with these shortcomings, and you have PLENTY of countertop space with plenty of air flow, it is a good unit to have.
As far as reliability and length of use, I will follow up in time.
