1. I wanted the GoPro for plugging the USB cable does not always have to take out of the housing.
2. The sound quality is very poor with the supplied housings. Through open are the mics I had hoped for a significant improvement.
Since the delivery I give the GoPro actually out only in exceptional cases, from the frame. The USB cover the GoPro is almost always open. And here is the only one from my perspective, gross lack of frame to see: SD card and HDMI connection is not accessible when the frame is mounted, here the camera has to be taken only out of the housing.
and there is no protective cover for the connections on the side of GoPro. If one wants the ports (actually yes only the USB port) to protect, so that GoPro has to be taken out of the frame here again.
I use the GoPro rare in situations where I need the water density or mostly spray-proof housing, the frame is sufficient for my needs from here completely. On the lens is currently under a protective glass, therefore this is also protected from outside influences.
This attachment is so simple and useful that it should belong in the GoPro in the standard delivery.
Ergonomic one could solve the connection problem better.
Another shortcoming is the high price. There are many "clones" that are much cheaper and would perhaps suffice for the simple purpose also.
