I bought this for two reasons, first, when my GoPro is in his XSource case that contains a storage net on the flap by, tended to be switched on by the presence of accessories that came during transport fit between the top of the carrying case and the camera, and from reliance upon the power-on button, and so drained the entire battery before having to use the camera!
The second reason is that when the camera is positioned in the desired position, awaiting action, I often find myself with fingerprints of my children, too curious to touch the GoPro placed as a filming one of their activities !
Having bought this little accessory has resolved these two problems. It is held firmly in place, it really does not move the lens cover is very effective to protect against dust too!
In short I recommend this product which is built in a sufficient quality plastic and conforms to the objective of use, plus the price is very small, which only adds a star!
Delivery: A little long, though I received with 5 days ahead of the maximum time announced, but it comes from afar ...
Packaging: Shipped in a paper envelope bubble risks are moderate when an alteration has such a small product that is more flexible, so RAS.
