A friend of mine ordered 4 pairs of these google cardboard headset kits to keep around his office. When they arrived, I helped him set them up and test them. The kits were easy enough to assemble, and they did provide a decent VR-effect. I felt that the lenses could have been higher quality, though perhaps they are the best ones available for the price. I also would have appreciated some headstraps so that I didn't need to hold the device directly to my face. Certainly a fun gimmick, with some definite potential, but I have to imagine there is room for significant improvement.
