This suction cup is great for shooting car rollers, or even different angles of yourself driving. It's a 6" suction cup, so I definitely feel more comfortable with it versus some smaller ones. The build feels strong, durable, and it's been able to handle up to 60mph in my experience so far. Overall, I'm satisfied with this suction cup.

What I use it for:
- shooting car rollers
- different camera angles for driving
- shooting driving b-roll

What I use it with:
- Primarily the DJI Action 4 and Osmo Pocket 3

I'd recommend to use safety cables/tethers with this suction cup, just as an extra safety measure.

Lots of metal.... durable rubber.... solid magic arm.... Everything you need.

My truck and my car are both primarily aluminum, and magnetic mounts just won't work. This K&F Concept 6" mount, however, does not rely on magnets, holds firm, and is super easy to check if it still has suction. Simply press up to the flat surface, start pressing the button to create suction, and keep pressing until the white suction line disappears. Easy peasy....

The "cheese plate" mounted to the suction cup gives plenty of mounting options, however, I really like the provided magic arm. It holds firm AND has locking pins. Nice....

So where does this work? Per the manual...
- On on smooth, flat, non-porous surfaces.
- Car speeds below 80km/h
- 0 degrees Fahrenheit to 140 degrees Fahrenheit

I suctioned this on my smooth fridge door (not bumpy, perfectly smooth) and it kept perfect suction for over 24 hours.

Where is this not to be used? Per the manual....
- This is NOT recommend for skiing, surfing, rafting, or other high impact/intensity sports. Additionally, there is some felt material behind the suction cup which probably shouldn't get wet.
- On paints surfaces, marble, old tile, wallpaper, rough glass or breathable materials... With that said, I suctioned this to my eggshell finish painted wall and it held well, though I didn't leave it on there long. So it will connect, but given the difference in smoothness and finishes of painted walls, I understand why it isn't recommended.

I'm really pleased overall with the quality. Not planning to use this at high speeds with my car, but will be good for filming with my Canon R50.

You know those action movies where they're using suction cups to climb plate glass skyscrapers?

Yea, this thing has just about enough power for that. I put it on my shower wall as a test and lifted myself up.

Cons: I'm not seeing any, though I'll definitely let you know in the future if the magic arm goes wonky like many others have on me in the past.

Pros: ULTRA SUCTION. I am about 70 kilograms on a good day. This thing held me for five seconds then I had to let myself down because I couldn't hold myself up like that any longer. Couple of attachments for other camera mounts or your phone, magic arm for swing-mounting and custom positioning, and some stuff for maintenance rounds out the overall package, along with manual and warranty card. As long as this can get a decent seal, it will grip and hold. The white safety line lets you know if your pump seal is getting weak so you know to give it a few more pumps to redo the seal. Breaking the seal is very easy even though it can hold a lot of force.

Definitely a good product. I'm gonna try using this for a dashcam mount in my car, if the textured dash isn't too textured!

Holds very well
Had the suction cup on the windshield for 14 days and it hasn't even come off.

The workmanship is perfect.

This is incredibly strong and held for a long time. But it's a big beast. Overkill for an action camera. Great for DSLR.

Used it to film my driving shenanigans and it did hold. The quality really surprised me, because everything is metal, the magic arm can be positioned in any angle and the cup itself is really easy to use

Very unstable intermediate joint. This can barely be turned firmly. Everything shakes with minimal shocks and you are afraid that it will break.

Update:
After contact with the very good customer service, a replacement delivery was immediately offered. Here, the joint has been modified somewhat and the screw connection can now also be tightened firmly. It's all right that way.

This product was sent to me for review as part of the Amazon Vine program. The following reflects my real-world experience using it.

I requested it because I use several action cameras (such as the DJI Osmo Action 5 and Osmo 360), and I thought the mount would open up some creative possibilities for shooting using my car.

It is a good-quality piece with a robust, sleek, compact design that makes it easy to store in a camera bag (or a car boot). The suction cup's secure locking system gives it a firm grip, while the adjustable ball head has a smooth movement that allows for more precise camera positioning. Having attached my Action 5 Pro, I would say that the mount holds it pretty steady.

In summary, an easy-to-use and good value item.

great super professional product

I was really satisfied with the K&F Concept suction cup mount during my first tests.
The suction cup is absolutely tight — even on the car window at higher speeds, nothing has come loose.
The workmanship looks high-quality, sturdy and the material makes a long-lasting impression.
I find the flexible Magic Arm particularly practical, with which I can perfectly align my Insta360 X5 or even my mobile phone.
The load capacity is absolutely reliable and the suction cup remains strong even after being moved several times.
An accessory I can rely on for dynamic recordings in the car or on the go.
