Not bad. 748

There is obviously nothing to say about the price compared to GoPro products.
In terms of quality of the whole, that's okay. Velcro seam has already dropped at the wrist scratch for the remote (okay, I was not in the utility)
Plastics seem correct quality, ds see the future for its strength. The GoPro housing fits very well and there are no games to the fastenings.
Bust tested: once properly adjusted and tightened, great, rendering movies is really nice.
The headband: easy adjustment, there has even slip inside elastic straps. Even on my head shaved, it does not move.
Finally, the whole is really correct. I could have put 4 stars but I put 3 because of the seam that dropped and because I express doubts about the strength of the material in the event of heavy use.
