I loved the small size of this unit and that the holder pivots from a 180 degree angle to a 90 degree angle which makes filming something at different angles really convenient. The problem is that the motion detector is incredibly sensitive and it is difficult to figure out what it is responding to. While sitting perfectly still the unit moved back and forth several times before standing still. I think there may be a learning curve to figure out how to make it work effectively for you if you want your camera phone to follow your movements. You really have to have the motion sensor pointed at the part of you that you would like detected which sounds obvious, but most of us are looking to see what's happening in the camera. I do like that it can safely and firmly hold your camera at different angles though. I wish I had it a few days ago while I was filming a video of myself. I will definitely make use of some of its properties, but as far as the movement tracker is concerned, I think it is too sensitive. One more positive point---you can unscrew it from the base and screw it onto some other tripod you may have laying around.
