ya get what you pay for... get a GoPro Hero 6 with a stabalizer... all you’ll ever need!
I have a GP 5 and am impressed with it.
It sits in the truck console most of the time, I’ve used it seriously two or three times.
My GH4 doesn’t see much use these days either.
I have a few things going on and playing with the cameras simply hasn’t happened.
Sorry, 400.00 is way to much
