Product review (3 stars): It worked great to begin with then hasn't worked great since
I use this item 24 hours a day.  It worked great to begin with then hasn't worked great since.  The larger ice cubes don't work at all anymore.  I used the large ice cubes until that quit working.  Now I use the medium setting.  This is working fine and has been for about 2 months.  Only time will tell.
