This so called business is as bad as it gets. Not only do they charge you $22.00 to ship 2 pairs of glasses they do so at the very slowest pace possible. These people or (person) that run this HDVision operation are as low-life as it gets. Ordered 2 weeks ago to have shipped from Calif.to Calif. Well $22.00 of S&H and 2 weeks later they still have not gotten around to even packing these for shipment. This company can clearly be called scum of the earth...
