I am on my third Opal in 7 months.  First one started making squealing noises the stopped making ice within a month, but it was given as a Christmas present so the purchase date was more than a month, I was sent a "refurbished" unit.  Missing screws, others not screwed in, it never was able to make ice.  It was returned and another brand new one purchased, after a couple months it is squealing and stops making ice frequently.  It goes into cleaning required mode hours after the last cleaning.  Very frustrating to have three of these in 7 months because each stopped making ice.  Looking to switch to another brand now, I am tired of messing with it.
