It's Amazon. Who hasn't used it before? It's pretty amazing what you get, especially if you pay the yearly "Prime" membership. You get free streaming video. Free music. Free shipping on all the stuff you buy on Amazon... What else could you ask for?
We used Netfloor USA for a project at a regional university in the Cleveland area early 2014. It went very well. We installed the access floor ourselves but they had a site supervisor out during the install to make sure it went OK.
We are actually going to be adding more access floor in the next few months in some of the other tech classes and computer labs. They were nice to work with so I thought I'd do them a favor of writing a review.
