I own one of these - bought it pre-made years ago rather than assembling the kit myself. It's a ton of fun, and really does give me a more-intuitive sense of direction. After wearing it for a while around places I go to regularly, I keep that intuitive sense of direction without having to wear it.
I've mostly stopped wearing it though, because it looks a lot like a GPS-based parole-monitoring device, and I got tired of questions/comments :)
