You need for the Gopro

This covers the protection of the lens both with and without housing should use really and always have. Not only are avoided on the glasses so that fingerprints, but also vorgebäugt scratches during transport in your pocket.

Normally, each camera has something to protect this besides just the GoPro. Therefore, the set is actually mandatory. It is a pity that the GoPro covers not equal attaches the camera :-(

In addition, the set for just a few plastic parts is relatively expensive. Here you pay well for the name GoPro extra again.

Conclusion necessary but 4 stars there, because this set is relatively expensive and not supplied with the same camera
