I bought the bundle actually solely because the chest strap and the handle to immerse me. But the chest strap from GoPro is expensive as the entire set, hence I thought to myself "Try before".
The delivery of my Prime subscription has always worked as quickly. Amazingly compact package came with me, I did not think that all the accessories fit into such a small package. In the package itself every single accessory or set was again individually packaged in small bags. This saves a then together seek :).
Like I said I have the package primarily ordered for the chest strap and the handle because I have the front and handlebar mount has original GoPro. Then I go back later on, finally I was able to compare very nice at this point :).
First the chest strap. The chest strap can be very well set - in all possible directions - and thus sits very close to the body (see pictures). For good shots this is very important in my opinion. As with the original chest strap, the camera is not directly attached to chest, but "clicked" on the quick release buckles and just as quickly again "be clicked" (see pictures). This eliminates the constant Unscrew when times would quickly change something in the settings, but the camera is seated very firmly.
The handle for the "Water Action" does exactly what it should. He lets the camera automatically float upwards, you should release this in the water accidentally. By color the GoPro then falls quickly in the eye, you should have lost sight of. On the other hand, it is not difficult to hold the camera with the handle underwater - so there is no strong impression and is not strenuous. Qualitatively this handle is of course not to compare with a telescopic pole, which I prefer in the water or for dives.
The headband differs visually only very very little from the original. I personally like the original headband however much better. Why I explain below. The setting options are really good, as good as the original. However, several small "rubber legs" zigzag processed like the original on the inside of the headband, which the bear again additionally stabilize and make it non-slip (see photos). In this bracket is processed on the inside a little, but only a thin strip, but that's not enough in my opinion out. If you want to support this, for example. In Parkour or football wear, I would probably still have recourse to the original holder or a product of any other third party. That's why only 4/5 stars, here the only criticism. However, one must at this price anywhere compromising course !! :) (Unfortunately there is only one photo of the original holder, because I have the support of this set without thinking away right away. I'm sorry)
The handlebar mount is really as good as the original holder. Apart from the visual difference, for example. However, when the screws I can not tell the difference in the use. Top!
All in all a really great set. The only criticism I think is the head mount, but hey, at this price you have somewhere of course compromising. The entire set is so expensive - in some cases even cheaper - as an original holder. In my view, you do nothing wrong here, whether professional or beginner. So it does not hurt to buy this set and easy to use the head mount times, then you can still buy another. I will continue to buy third-party accessories. Someone has also said beautifully in another review: "At the end eh everything comes from China."
I hope I could help you a little. Unfortunately some pictures are missing, the reason is that I have some mounts further away directly or they do not have just to currently available. For further inquiries, I am happy :) available.
