Just got the Opal 2.0.  Set up was rather easy, started making ice within 15 minutes.  Only concern is that the tube to the side tank can come off very easy, which is not good as don’t need a gallon of water draining out.  Need to get a clip of sort and clamp the hose on.  I already popped it off when getting moving it to get info off back to register.  Outside of that, no issues noted.  Look forward to enjoying the ice.
