It's a GoPro counterfeit. You see, when Western companies send their tech to be manufactured in China, it's a given that those technical specs will be shared with all their "cousins," who each make their own counterfeit version of your product and flood the market with them.

Meaning you can't compete with the cheap knockoffs, leading to you losing market share and the Chinese scammers stealing the bulk of the market share at your expense. "Thanks, yangguizi!"
