Good price and delivery, image quality sufficient

The SJ40000 Wifi to the charger and second battery is really a P / L firecrackers: Large delivery, low price.

But:

-The Buckles do not fit properly in standard Gopro holder (Mantona, original Gopro). They wiggle back and forth, you have to put something under or terminals, ie only with the supplied clasps really good fit.

-The Picture quality is pretty bad when you can it as I compare. Excessive curvature, no true 60 frames per second at 720p60, the automatic white balance is not to be used (to bluish). White balance on Cloudy helps somewhat, but the blue sky will look to blue and all other Colour Bet strongly.

-The Buttons on the immersion housing are compared to Gopro very small and hard to use. One does not really have a good tactile feedback.

That's about it on the bad stuff, the rest is very positive! For me, anyway not the camera, as the image quality and the 60FPS me are important.
