The TLDR is they all use the same 2 chip sets and Sony sensors so it doesn’t really matter if you spend $70 or $300, the core function, that is the video quality is basically the same and ranges from ‘bad to slightly less bad’. That’s not to say that some are better than others when it comes to the total package.
Oh and unsurprisingly the Amazon reviews are fake.
