After seeing the $400 GoPro price tag, I went with the Ignite 4K Ultra HD for $219. It's an exact clone of the GoPro. Honestly I don't know how they do it without getting sued for patent infringement, but that's not my problem.
I use the GoPro dive housing that comes with the wristband just because the Ignite dive housing that came with it didn't have a wrist band attachment. It comes with an 8gig SD card but I upgraded to a 32 Gig SD card. So far I've shot 72 minutes of video on one battery charge. The video was 2.2 gig at 30 fps but the Ignite will do 4K video at 60 fps also.
The video is just as good and I like the rear LCD screen on the Ignite that lets me see what I'm shooting. Honestly I can't see $200 difference in the video between the pricey GoPro and the Ignite. I think you're buying a lot of name brand with GoPro.
