Delivery: in 1 business day so impeccable.
Quality: high quality (plastic and metal mixture) identical to the original GoPro. The screws have a slightly different design of the official. It is possible that the resistance (including shock) are still lower than the original, so I advise to combine the authentic and them. So this article includes a non-slip piece, not as the GoPro release. Unfortunately, this does not increase the adésion (because normally you have to bite as hard as possible), which remains the same but moves the camera when large shocks. But it is useful for narrower tubes and of course, it is easy to fall off.
Compatibility: 100% compatible with GoPro systems. Screws and "connections" GoPro is sometimes a little bit harder to secure because they do not come from the same machine. Just slightly more force and a long, plastic deforms and adapts.
Price: about 37 less, or 3 times cheaper than the official one, hard to beat.
