have had the previous generation Wrap product from Vuzix, and subsequently a rift DK2...I primarily used both to keep proficient in flight simulators. the screen door effect on the dk2 was unacceptable, even the previous product from Vuzix had better resolution and gauges were easier to read. head tracking was hit n miss on the vuzix and needed constant resetting. The rift may have a bigger field of view but the pixels are hence spread across a larger field of view, hence the screen door.
I now own the vuzix iWear, waiting for improved resolution from second generation rifts/vive/etc. Each product has it's niche markets and for now for flight sim'ing the vuzix is the way to go.
Different Strokes for different folks... and Vuzix, mtbs3d and the like is where P.Lucky really got his start
