Product review (5 stars): so far so good with the replacement ice maker.
i ordered one that i have sent back because it started sounding like the fan blade was hitting something. and out of line. it made great ice and was perfect for me with the timed on/ off feature.  i ordered a replacement and waited for it to arrive before sending back the original.
i have cleaned and tested the new one.  it is set to start making ice for me to use in my bar.  have it set to go on at 3pm and turn off at 6pm.  will see how it does tonight.  if it does meet my expectations over the next week or so will give it a better rating.  i liked it well enough to replace it.  my sister in law has one for around 6 months and seems to love hers.  mine is silver and hers is white.
the replacement came in and has worked perfectly,  on at 3pm and off at 5:45pm.  its in international time.  on at 1500 and off at 1745 hundred hrs.  i could just leave it on all of the time but i only use mine for late afternoon drinks. i am very glad that i replaced the 1st one.  instead of just sending it back.
about every other day i use a Brita filtered pitcher to top off the tank.  the ice and water taste is the best ever.  it sure beats paying $1200. for a new ice machine.
