Product review (3 stars): Unit works well AND MAKES GREAT ICE, FAST
Unit works well AND MAKES GREAT ICE, FAST, but failed due to corrosion after 6+ months.  When the ice tray gets full, ice can rest on the LED transmitter on the left-top of the unit and the sensor on the other side.  Regretfully they are both well caulked from the back-side but not from the front (ice side) allowing ice to melt onto the LED causing failure that resulted in equipment shut-down because the sensor thinks the ice tray is always full.
A small amount of clear silicone around the base of the LED would have prevented the problem.
