Not playing with a full deck.
Product seems ok. I bought "used in good condition" but it's missing a pair of parallels. The box is beat up but I guess that could be expected if it was returned. Im not scoring this low since it isn't the mfr's fault. It was "inspected by Amazon" but I guess they can't count to 10.
