Giving a 5 star just to be a nice guy, and I am satisfied with the protectors. I paid extra for an express shipment only to be informed afterwards the express shipping only starts after the product is made - days later. They admitted the shipping is misleading. As a retired Engineering Manager with extensive hands on design / shop floor manufacturing process experience spanning over a 40 year career, I have a pretty good handle on what the "manufacturing product cost" is for these. With these "prices" they sell these for, they're making a tremendously huge profit margin.
