    • Good product poor packaging

      The product arrived broken due to the packaging for the us mail. I contacted the customer service about the damage and after a period of time they sent me the parts to repair it. The unit just fit in the shipping box which didn't allow for a proper cushion for the beating it takes in the us mail. The product now works fine.
