When you are looking for a mounting system for recording from the car, the difference between a mediocre product and a good one is obvious from the first moment you have it in your hands. With this K&F Concept kit, the feeling is immediate: everything is metallic, everything is well finished and everything transmits solidity. No plastic that creaks, no pieces that look like they're going to break on the second exit. K&F Concept is a brand known for making serious photographic accessories, and this kit doesn't disappoint.
The pack includes two 3-inch suction cups, and here's one of the great successes: having two of the same size gives you enormous flexibility. You can use a single one for simple setups, or combine both to build more elaborate and stable configurations. The suction cup is fixed with a lever system that generates a very powerful suction on any smooth surface: front window, rear window, hood, roof, even flat metal surfaces of the body. Once fixed, it doesn't move. (In my experience, the surface must be smooth, otherwise the suction cups come loose over time) The magic articulated arms are
the lifeblood of the kit. They work with a central ball joint that, when you press the throttle control, locks the position at any angle you need: tilted, sideways, downwards, upwards. What seems simple is actually what is most appreciated in real use, because you can adjust the frame with millimeter precision without having to disassemble anything.
How to make the most of each accessory Front
window suction cup + short magic arm → Driver's POV The most classic combination. It is fixed in the lower corner of the moon, the arm orients the camera towards the driver or the road, and you get that first-person shot that looks so good in road videos or sports driving videos.
Suction cup on rear window + long arm → outer rear plane By fixing the suction cup on the inside of the rear window and extending the arm, you can achieve an angle that simulates an external camera following the car. Ideal for travel videos or network content.
Suction cup on hood or outer roof → zenith or front plane The suction cups hold up well at moderate speeds on smooth outdoor surfaces. With the arm facing backwards on the hood, you get very cinematic shots that would normally require much more expensive equipment.
Two combined suction cups with a long arm between them → maximum stability Using the two suction cups as anchors at two different points in the cabin and the magic arm tensioned between them, the stiffness of the set increases significantly. Perfect for heavier cameras or for surfaces where a single suction cup doesn't give you all the confidence you need.
Action adapter + mobile clip → total device versatility The included adapter allows you to connect GoPro or Osmo Action action cameras with standard thread, and the mobile clip adds the possibility of attaching a smartphone directly to the arm. Thus, the same kit is used to record with the action camera, with the mobile phone, or with both in dual configurations.
Outside the car → emergency tripod or study arm The magic arms with suction cup also work attached to any smooth surface indoors: window glass, glass table, mirror. Useful for vlogs, video calls or creative montages at home or in the studio.

Note for connoisseurs:

Given that K&F CONCEPT is a reliable brand with an impressive quality/price ratio, this support kit has been designed to allow the attachment of action cameras, mobile phones and cameras thanks to two suction cups and a magic arm. This tool is a useful solution for those who want to record videos from different angles. I decided to test it during a track test in a sports car. Impressive.

The installation was direct and intuitive: I fixed the suction cups on a flat surface of my vehicle and mounted my action camera on the articulated arm. The grip was pretty solid and I was able to record without problems, even during the sharpest turns.

Among the positive points there is certainly the versatility of the adapter, capable of supporting different devices, and the ease of assembly. On the other hand, one of the disadvantages is the durability of the suction cups, which could be compromised in prolonged vibration conditions or on rough terrain. In addition, adapting to heavy cameras can put a strain on the system.

In summary, the K&F CONCEPT kit offers good performance for hobbyists and amateurs who are looking for an easy way to mount their cameras during outdoor activities. It is a good product, although there is room for improvement when it comes to stability on difficult terrain.

This set is ideal for temporarily attaching an action camera to a vehicle, thanks to its two suction cups it allows you to do so without leaving traces on the vehicle!
It is accompanied by a small magic arm to orient your camera on it in the desired orientation, a smartphone clip.
The suction cups hold well, I have less confidence in the magic arm and if I want to use my iPhone then I prefer to put it in a dedicated cage screwed onto the magic arm provided (or another one).
In short, very useful for filming in a car, I wholeheartedly recommend it.
