Wanted to get a Go Pro a while back but didn't want to spend the money. Now there are a lot of knock offs that come pretty close for $100 and under and do a great job. BUT before I found them I got the Polaroid Cube which I mounted on the rear of my DJI Inspire 1 drone just for fun. It mounts with a magnet and holds very well. It records in 720 or 1080P and records in 5 minute segments. I have mounted it to the front of my Kodiak and shot some good footage but this is the only one I have to share.
