Much improved version of the previous model. We loved our Opal 1.0 but it should have lasted longer than 506 days from purchase. I bought the new version after reading about the improvements and hope the new version outlasts the previous one. Once you have the "good ice" in your household it's hard to go without, it's among the most used appliances in our home. Much quieter than it's predecessor and cleaning / descaling / disinfecting seems to be quicker on the new model.
