K&F Concept 6" Suction Cup Camera Mount with Magic Arm

Works good for what its called to do

Excellent solution for video work whilst driving. or for a very secure tripod mount that you can keep in your vehicle full time. That's where I keep it now.
The suction works very very well...I could not budge it in any way. I would trust my gear on it.
The base is solid metal...very stout...with a plethora of attachment points. Also included is a small camera mount that keeps stable using O rings. I think I would definitely feel confident with a 'GoPro' type product with this mount, but I'm going to balk at using my full frame camera on it.
Which leads me to a very slight ding and suggestion to K&F. It's a great design, but if K&F had simply added a male to male short thread to go into the base...then I could add my mount on it. That is exactly what I ended up doing. Luckily I was able to purloin the needed male to male connector off of one of my travel tripods. Once that is inserted into the base, then anything you want to add to it...ball head...fluid head...even a gimbal is now possible. I don't think the added weight is any concern to the product...it's grip is a beast.
You can see the ball head I attached in the provided images...now that is a nice set up.
Excellent product otherwise...and still a strong 5 stars.

This suction cup camera mount is an impressively robust bit of kit that balances versatility with build quality. The first thing you notice is the sheer size of the suction cup – it’s large, heavy duty, and inspires immediate confidence. Once it locks on, it stays put, whether that’s on a window, desk, car panel or even a smooth painted wall. The pump-activated suction system even has a built-in safety indicator so you can monitor it over long sessions.

The mounting plate is well thought out, with multiple 1/4" and 3/8" ARRI holes and even a slot for a safety rope, giving you huge flexibility for attaching accessories at different angles. Out of the box you get a magic arm, phone holder, and GoPro/action camera adapter, making it just as suitable for smartphones as it is for dedicated cameras.

The included magic arm and dual ball head system makes framing shots easy, with smooth adjustments and good friction from the rubberized rings. For lighter setups like phones, action cams or compact mirrorless cameras it works flawlessly. With heavier DSLR gear, it can hold steady but you may notice a little flex in the arm – in those cases a sturdier arm might be worth adding.

Several reviewers compared the suction to professional-grade glass lifters, and the consensus is the same: this mount grips with real authority. It’s solid enough for time-lapse, vlogging, travel shots, and even car filming if you’re brave enough to mount it outside (though some users admitted they haven’t worked up the courage yet).

Build quality overall is excellent – metal hardware feels strong and durable, while the only slightly weaker link is the plastic suction cover, which feels cheaper than the rest of the kit. That said, in use it doesn’t affect the actual performance.

Price-wise, it’s not the cheapest option out there, but the extra spend is clearly reflected in stability, strength and reliability. For creators who don’t want to risk gear crashing down mid-shoot, that peace of mind is worth every penny.

In summary:

Strengths: exceptional suction grip, versatile mounting options, solid construction, includes useful accessories.

Minor Weaknesses: magic arm flexes slightly with heavy DSLR setups, suction cover feels cheap.

Best for: phones, action cams, mirrorless and lighter DSLRs; creators doing vlogs, time-lapsing, car shots or multi-angle setups.

Overall, this suction mount earns strong 5-star praise across the board – robust, flexible, and reliable, with performance that far outweighs its price tag.

I've been really impressed with this suction cup mount so far. It's solidly built, made entirely of metal, which gives it a premium feel. The included magic arm is also well-constructed and feels very sturdy. The suction cup itself is quite strong and offers excellent holding power. I've used it with my Sony a6700 without any problems. For flat, stable surfaces, I’d say it’s more than capable of supporting an average-sized DSLR.

If you're planning to use it for car-mounted shots, I’d suggest using two or three together for extra security (which is definitely possible). It’s always better to be safe than sorry.

All in all, another excellent product from K&F. Highly recommended!

I am not a professional photographer, but I do enjoy going out some days and focusing (excuse the pun) on specific objects, and experimenting. I do have a 35mm camera, but these days, given the power of a modern phone, I tend to stick to this as my go-to tool of choice, the quality is good enough fo rmy needs.
I found this mount to be versatile in terms of the devices it is designed to hold, very well built and designed. It adheres well to flat surfaces, although I have yet to build the confidence to mount it on the outside of my vehicle when in motion....
If you seek an inexpensive versatile mount, then this might well provide you with a very good option.

The cost of this vacuum/suction mount is very reasonable for a 6 inch suction. The rubber suction is thick durable and malleable enough to secure to surfaces that are not completely flat. The solid aluminum base has several 1/4 20 mounting holes, 3/8 mounting holes Arri location anti-twist holes and the top of the aluminum base has angled sides for more versatility with mounting options. Adding to the versatility is the accessories, the fully metal magic arm, the GoPro adapter and the phone adapter makes for a lot of options to mount different accessories. This suction cup is very easy to use, place the rubber suction on a clean surface give the plunger a few pumps until the safety line on the plunger disappears and its ready to go. Because of all of the holes the accessories the wide base makes this suction very functional.

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.

I have so many of these kinds of suction cups, but the only ones i really enjoy are the ones with metal bodies. This one is in normal rotation because it has more mounting options at good angles. ARRI locating pins all over, so things will stay locked in. I like to test these on my sliding glass door in the sun with a water bottle hanging off to see how long they last before they fail. This one has been on my door for about 5 days so far and hasn't lost suction. I'd say it's made very well and is reliable enough for what i'd need.

This 6" suction cup camera mount is a highly practical tool for photographers and content creators seeking flexible mounting options. The strong suction cup securely attaches to smooth surfaces, from car windows to polished countertops, providing a stable base for cameras, action cams, or phones. Equipped with a dual ball head and magic arm, it allows precise angle adjustments, making it easy to frame shots perfectly from any perspective. The mount accommodates both 1/4" and 3/8" ARRI holes, ensuring broad compatibility with devices like DJI GoPro Hero 13, Insta360, and smartphones.

Setup is straightforward, and the mount feels solid and reliable during use, even with heavier cameras. The phone holder adapter adds extra versatility, allowing smooth transition between professional cameras and handheld devices. This mount is perfect for travel, vlogging, car filming, and time-lapse photography, offering a stable, portable, and adaptable mounting solution for creators of all levels.

I’ve been using this suction cup mount for a few weeks now, mainly with my GoPro, and I’ve got to say, it’s been one of the more reliable mounts I’ve tried so far. I’ve gone through a bunch of different suction mounts over the years—some cheap Amazon ones, a couple of “name brand” ones—and honestly most of them either don’t hold well, or they feel like they’re going to give out the second you start driving faster than 30mph. This one actually feels trustworthy, which is kind of the number one thing you want when you’re sticking a £400+ camera on the outside of your car.

The suction itself is crazy strong. Once you clamp it down and lock it, it’s not going anywhere. I’ve had it on my car roof, hood, and side windows, and it hasn’t budged even when I’m doing motorway speeds. I even tried it on some rougher back roads just to see if it would slip or rattle loose, and it stayed rock solid the whole time. That’s a big deal because the last thing I want to be thinking about while filming is, “is my GoPro about to fly off?” The locking mechanism is reassuring too—it clicks into place firmly, and you can feel it bite down on the surface.

The magic arm setup is honestly one of the best parts. The dual ball heads give you so much flexibility to get weird angles. I’ve used it for low-to-the-ground shots while the car is moving, and also from higher up angles looking down, and once you tighten it in place, it doesn’t drift or sag. I’ve had other mounts where you set it up, start driving, and by the time you look at the footage, the camera angle has slowly shifted downward. This one locks tight and actually stays where you want it.

Another thing I like is the included adapters. It comes with a GoPro mount and a phone holder, which I didn’t think I’d use much at first, but it’s actually pretty handy. Most of the time I’ve got the GoPro on there, but I’ve tried the phone mount too for some behind-the-scenes clips, and it held my phone just as securely. Nothing wobbly or sketchy. It’s nice having that flexibility without needing to buy extra adapters.

Build quality is solid overall. Nothing about it feels cheap. The suction base is sturdy, the arm is metal, and the knobs feel strong when you tighten them. I’ve adjusted it a ton while figuring out shots, and nothing has loosened or started to feel flimsy. I’ve had some cheaper mounts where the plastic threads strip after a couple uses—this doesn’t feel like it’s going to do that. It definitely feels like something I’ll be able to use for years, not just a “one project” kind of thing.

Setup is pretty straightforward too. As long as you’re sticking it on a smooth, clean surface, it attaches quickly and locks down firm. I’ve mostly used it on glass and car panels, but I tested it on my desk just for fun and it clamped down like a champ. Out on longer drives and bumpy roads, the GoPro stayed put—no vibrations ruining the shot, no slipping. That’s huge when you’re trying to get cinematic-looking car footage without messing with rigs or gimbals.

Now, a couple of small downsides. Because the suction is so strong, you really want to make sure the surface is spotless before sticking it on. Dust or tiny bits of grit can reduce the seal a little, and also I worry that over time it might scuff paint if you’re not careful. Not a big issue, but something I keep in the back of my mind when I’m mounting it to my car. Also, it’s not the most compact mount once it’s all assembled. If you’re packing light, it takes up a bit of bag space compared to simpler mounts. But honestly, I’d trade a bit of bulk for the security and stability any day.

Overall, I really trust this mount with my GoPro. It’s strong, versatile, and hasn’t let me down so far. The fact that I can throw it on in seconds, adjust the angle however I want, and then just hit record without stressing about the camera falling off is worth it to me. For car shots especially, it makes life so much easier. Definitely one of the better mounts I’ve used, and I’d recommend it if you want something reliable and flexible for both GoPros and phones.

I hope this review helps someone out.
