So, the 6-inch suction cup mount from K&F Concept is a real highlight for anyone who regularly films with a camera or action cam in the car. The workmanship is impeccable, the suction cup sticks so firmly to smooth surfaces (e.g. glass, bonnet, side windows) that you almost have trouble releasing it again!

Particularly noteworthy is the combination of a strong vacuum foot (up to 60 kg horizontally) and the flexibly adjustable Magic Arm with ball head. The adjustment is quick thanks to a single wing screw, but is then bomb-tight. 
I've tested the setup with my Sony RX100 VII so far and plan to use it with the Alpha 7 IV, it wasn't a problem for this mount.



The included adapters for action cams and smartphones make the mount universally usable, e.g. for Insta360, DJI Action or GoPro. The 1/4” and 3/8” connections, including ARRI positioning holes, allow additional accessories to be securely mounted without anything twisting.

My personal conclusion as a full-time video grapher/photographer:

For anyone looking for a stable, low-vibration solution for shooting from the car, this mount is a real asset!





The 6-inch suction cup from K&F Concept makes a very robust and confidence-inspiring impression. The large suction surface ensures a stable grip on smooth surfaces such as glass, metal or car paint. The ball head with Magic Arm offers many adjustment options so that cameras, lights or accessories can be flexibly positioned.

✅ Positive:

Very strong adhesion - holds reliably when the surface is clean and smooth

Flexible joint system — ball head & magic arm offer many angles and creative mounting options.

Good workmanship - feels solid and durable

Load capacity sufficient for compact cameras, monitors or LED lights.

This is an excellent bit of kit, really very good indeed.

The main part is the vacuum clamp. It's as good as some I have for lifting large glass sheets, so really very good for a camera. You'll need a fairly flat surface that's smooth and able to take the clamp all round without leaking, but that's most car panels, windows, even smooth painted walls. Very strong suction indeed.

Once clamped it's easy to add the brackets for universal action camera mounts or standard tripod thread. The articulated bracket can clamp tightly to be very rigid. Easily takes a medium sized lens on an SLR for example.

Great value, well made and functionally does more than I'd expect.

⭐⭐⭐⭐⭐
The K&F Concept 6 inch suction cup mount comes with German instructions, Allen wrenches for tightening, rubber sealing rings, a mobile phone holder, an action cam mount and a magic arm.
The suction cup is very robust and made of plastic, silicone and a metal body. You can attach accessories with multiple threads.
The Magic Arm is also very well made and robust. It is made entirely of metal and can be adjusted at different angles at two joints.
You can then either use the plastic mobile phone holder (which is significantly better and more valuable than the typical holders that are included in this way) to attach a smartphone, or attach an action cam or even a system camera.
The holder is really super secure, as it is sucked onto the window with a pump mechanism and then holds firmly.
The mount is very well made and easily suitable even for professionals.
Highly recommended for the price!

“Wow... that thing is big.” We photo and videographers are certainly not hearing this for the first time. However, this was more limited to the camera, lenses or light shapers. But this time it's about a mount and it measures no less than 15cm in diameter. In addition to the actual suction cup with adapter plate and pump, a holder for action cameras and mobile phones is also included. This is complemented by a Magic Arm as well as Allen keys and rubber rings. Quality is everything really well made. The adapter plate gives you plenty of options for attaching your equipment and the suction cup itself does what it promises. I wouldn't be afraid to mount my camera here. Should you be unsure, the adapter also has the option of attaching a safety cable. Overall, the whole product looks very coherent to me.

This setup is a beast! Huge suction cup that doesn't give up and solid base, feels like it was built for a tank.

I liked it a lot

Great item

I originally bought this suction cup mount for car filming. I do some content creation for my business, and when I get phone calls or moments that are good to record, I want to be able to capture them right away. I drive a truck and quickly realized there really isn’t a great built-in place to mount a camera, so this seemed like the right solution.

I’ve had it since October 2025 and use it occasionally, not daily. I mainly mount my Sony camera on it, and that was my biggest concern. It’s an expensive camera, so I needed something that felt genuinely secure.

After using it in the car, I started finding more uses for it. I’ve mounted it to the windshield while someone else was driving, used it on a whiteboard in my office to record while I’m working, and even brought it golfing. That was probably the real test. The cart went over concrete, grass, and uneven trails, and I was honestly skeptical at first. We even had someone ready to catch the camera just in case. It never fell. The suction held the entire time.

The suction strength is extremely strong, and the magic arm is very flexible. You can adjust it to pretty much any angle you need. The quick release works well too, just don’t overtighten it. Once it’s locked in, it’s really locked in.

The build quality feels solid overall, and it’s given me a lot more confidence mounting my camera in places where I normally wouldn’t risk it. If I had another camera and wanted to cover more angles, I’d buy this same mount again without hesitation. At this point, it’s field-tested for me.

It’s great, used it for an Insta360 camera with the stick extended about 3 feet on the outside of a window in the snow worked perfectly. Didn’t slip or move at all, very impressed with how strong it is.
