WiMius camera. Any good?

Been looking around for some cheaper alternatives to gopros because I’m cheap. And also because I’d like to have more than one camera setup.

I heard from a coworker that bought one of these, that they’re actually pretty damn good for the price. I’m probably gonna pick up two and put them thru the paces once I get back home.

Has anyone else heard of or tried one of these?

Seem to be a lot of GoPro knockoffs in about that price range. I’ll be interested to hear how it holds up...
