Product review (3 stars): Arrived but not in working order ...
Not our first Jet Stream so we are familiar with benefits and weaknesses.  We know the belt to be a problem on the older models which this apparently was though setting on a shelf somewhere as it was new.  However, we contacted the seller through Amazon and arranged an agreeable  price adjustment if we retained the unit and replaced the belt.  Though a little noisy, works fine with the replaced belt.  The seller was most cooperative so the 3 stars has to do with the design rather than the transaction.  We are informed via online queries that the newer models, though more expensive, do not have a belt.
