As Sheldon Adelson (sold Comdex and current owner of the Venetian Casino in Las Vegas) told me a few years back, "Copy from the best!”

And, that's exactly what we've done.  CustomInk starting showing reviews online several years ago and we launched our own version today.  On the surface (and when I first saw it), it seems like a marketing gimmick and, as some of their press releases reference, crazy for a company producing custom goods (since customer input is an integral part of getting an order right)  

They created transparency and risked their reputation doing it.  That’s the point.  Create a method for feedback so you can learn from your customers and then display it to potential customers as a certificate of your reputation.
