Product review (4 stars): We're hooked!
The unit we received worked great for 12 hours, then shut itself off and could never be turned on again.  :-((  However, the folks at Luma did a great job of replacing that unit.  They sent a prepaid label to send the original unit back and a brand new unit arrived before we even had a chance to have FedEx pick up the one that needed to be returned.  The customer service people were really easy to deal with and very responsive and capable.  I was really impressed that there are still companies willing to stand behind their products in the way Luma did.  The replacement unit has been working flawlessly for about six weeks now.  We turned off the ice-maker in our freezer and my wife transfers the clear ice to the ice holder in the freezer.  So we don't have cloudy ice anymore!  The clear ice looks and tastes soooo much better.  We use bottled Arrowhead water to make the ice.  Obviously now that we're addicted, we'll be very happy customers as long as it keeps working well.
