I was a bit nervous to purchase a refurbished unit, but I knew that this would be a secondary coffee machine for me, not used every day (I have drip coffee daily). It has worked well, I've used it about 10 times. The shell on the top of the unit is uneven down the center seam - I suspect that is why it had been returned to become a refurbished unit. The unevenness is just cosmetic and does not affect the function. Overall I'm happy with this unit and would purchase again.
