FYS"how often do you shake your cards? More than a paint shaker? jebus"
The paint shaker experiment is an excellent marketing ploy and does win over those that wish too be and those that do not understand the physics of a paint shaker vs. dropping a slab from 4 ft i.e. standing position. The paint shaker does not exhibit the extent of a direction force that is experienced when a slab impacts on a corner, which can and will cause damage to a card. I damaged two PSA 9 cards back in 1999 by accidently dropping them from a standing position. They hit the concrete on a single corner and both cards were damaged. I was never comfortable with the loose fit of the cards, but that incident single handedly moved my business to SGC. The half grade system, customer service, consistency and increased trust were icing on the cake.
