I have a love-hate relationship with my Opal. When it works, it makes amazing ice. After a month of ownership, we returned it and GE sent a replacement because the original stopped working. We are right at a year with the 2nd one and we have cleaned it regularly.  This latest cleaning has not resulted in making ice consistently. I have cleaned it with the suggested bleach-water ratio and it made ice for 2 a day. Cleaned it again with the vinegar-water ratio and  it made about 100 pellets and then stopped again. Unplugged it for a day and turned it back on and it made another 100 or so pellets. We are in a funny time, past the 1-yr of the original purchase but just under 1-yr with the replacement.  Will be curious if GE stands behind their product when I reach out to them.
