From the K&F brand, of which I already own many products, I expected excellent quality, and I was not disappointed.
This POV kit is almost complete, even abundant in some details.
POV, point of view, literally point of view, but in practice it is used to indicate a first-person point of view, as if the camera were our eye.
So we are dealing with wearable accessories, so as to film everything from our point of view and not, for example, from the handlebars of the bike.

So we have:
An arm band
A chest harness
A head band support
A belt or backpack shoulder strap clamp
4 quick-fit supports complete with fixing thumb screws for the camera
A 90° extension
A screw-on support with ¼"" male thread
A smartphone support

In short, an arsenal to be able to attach the action cam (or the phone) to different parts of the body.
All the textile material, bands, straps etc. are of good quality. On the headbands there are also non-slip silicone bands, in the part in contact with the body.
The backpack clamp is very sturdy, with a very strong spring and teeth that prevent it from moving.
The plastic parts appear very solid.
The armband, placed on the wrist, tends to twist under the weight of my Dji, which is quite heavy and I have a very thin wrist. Placed on the bicep, no problem.

The whole thing is compatible with the classic ""gopro type"" supports, therefore with thousands of action cam models, including the Dji Action 5 pro which was my model for the photos.
I took at least one for each accessory, so you can see what we are talking about.

Highly recommended kit.
