The worst part was the mode where it follows you around. There is only one device on the market (airdog) that does that, and it requires you wear a special RF beacon and doesn't work that well. The zano was meant to follow your phone's GPS (which isn't very accurate) and they didn't specify how it managed to keep you in frame. I suspect it didn't. Also, no way in hell are they getting more than five minutes flight time out of the tiny battery they showed.
