Product review (1 stars): If you buy this, purchase earplugs as well
This machine is so loud that it is unusable indoors.  It isn't supposed to be used outdoors so it is basically an unusable piece of junk.  I bought mine from Kegerator instead of Amazon which was a huge mistake since Kegerator won't accept returns without the original packaging and their only advice to me is to call the manufacturer.  The poor customer service is secondary to the poor quality product.  It seriously is louder than a car idling.  Even after enclosing it in a cabinet with insulation it is too loud to leave running continuously.  Lousy purchase; very disappointing.  I was counting on it for Thanksgiving.  I would give this zero stars if possible.
