Product review (3 stars): Clicking sound just before ice ejects.
Installation not too big a deal. However the gears the gear clicks about 14 times when the ice is ready to be ejected and the heat has not reached temperature.  After temp is reached, ice falls just fine and water refills. Sounds like a gear slipping.  Have to uninstall all of the parts and return it.  Can't just get the main part of the machine.  What a pain!
