I confirm compatibility with GoPro Hero 4, both in terms of tightening and positioning as slots corresponding to micro, micro SD, USB and mini HDMI ports, three LEDs, and the Setup button, commissioning in Power On and Shot.
Compared with Version GoPro Hero 3 has a system (disliked) to the back door for battery exchange, in this case the GoPro Hero 4, access to the battery is completely sealed, since the latter is on the bottom through a mini door, this involves a complete withdrawal of the accessories to change!
The plastic used to outline the framework is both flexible to allow easy positioning of the camera, but also flexible enough to take a position that enables it to properly fit the contours of the GoPro.
The accessory comes supplied with the outline of the GoPro, the male claw integrated system, as well as the traditional female claw support GoPro and a long screw type for easy tightening.
I recommend this product has a quality / price acceptable!
