Foxeer seems to have caught up with GoPro sometime around the GoPro 5, and all you’re paying for on the GoPro is the advertising and marketing overhead anymore.
GoPro like a lot of companies was once interested in producing a superior product for a decent price, but they found that marketing their own name so people (and early fans) never bother to look for their competition, made them a lot more money in the income side of the balance sheet.
If you actually look at the feature set and quality, they’re not that great anymore. Certainly not for often 300% more money than their competition.
Service and Support? Fine. If you’d feather have great support when you call to replace one of them when broken, rather than just have three whole cameras of equal quality or so close it doesn’t matter, for the price of one GoPro, that’s okay. Some people like that.
