I did a lot of research and was previously convinced that this would be perfect for my hybrid photography.
One should buy fluid head and that is the most economical in price but not in terms of quality.
I thought of Manfrotto BeeLive but it was too light and no monopod possible.
positives:
+ Very very sturdy
+ When extending 171cm from 191cm as a monopod
+ Panning is very smooth
+ Tilting is smooth as well
+ Ease of use
+ Good looking
+ We can fully control the rigidity of both axes of movement with the given screw knobs.
+ Can easily turn down the liquid head for a close-up shot
+ Can easily hang more weight with the hook to make it more stable.
+ Economical, half the price. Hold the liquid head and

If you want to use L-Bracket, you need to buy an adapter, the included quick release adapter perfectly fits any camera with 1/4 or 3/8 screw, but it is wider than common L-Bracket 39mm x 10mm.
3kg weight was not a criterion for me. Manfrotto BeeLive is 1.4 kg, but certainly not more robust. What I needed
was certainly a monopod.

- One will find it a bit confusing to balance with built in two mind levels. But you will soon learn.
We need to use the lever to pull so that the ball head will start tilting.
- The quick release plate could have been longer, 150mm instead of 100m which is supplied. It would have made the camera more stable with a longer lens. This would have made Panorama much better.

As a final criticism, I am very satisfied with the tripod and am looking for a long pleasant working with it.
I recommend it without hesitation.

I state that I already have a Manfrotto 546GB with a 504HD head (great headstand), I needed a second tripod but I had no intention of accessing a mortgage to buy it... so I will compare it to this...
what can I say I was amazed at the quality... I was expecting a cinesata but had to change my mind, large size, closed it is the size of a photo tripod, it has a fantastic carrying case, a liquid head with different adjustments, adjustments, bubbles, etc., dimensions during use both in height and in perfect dimensions, possibility of using them as a monopod.

Let's go to the dark side...
The weight is definitely not light, the head I still say good does not have all the Manfrotto head adjustments, for example the adjustable clutch for horizontal movement... which is present on Manfrotto and is not present here... but we always consider the price, the boom for moving the head is a little short and not telescopic, there is no three-foot base in monopod mode, so you get tired of holding it in place for long-term use. The hooks for tightening the tripod rods seem undersized to me, but it still does their dirty work.
Conclusion Manfrotto is still Manfrotto... but this Cayer surprised me.
... And good!

This tripod is a beast! Whilst it may not have the name "Manfrotto" or "3 Legged Thing" all over it, it is more than capable for it's price point!

Having switched to this from a similarly priced Manfrotto, albeit a much smaller tripod I am initially surprised with the similarly in quality.

Whilst the Manfrotto feels ever so slightly more refined, the K&F blows it out the park with height, versatility and ease of use!

I always found the Manfrotto locking mechanisms very small, fidgety and likely to give me small blisters from repeated adjustment. Whereas the K&F model has comfortably sized levers/screws.

The ability to dettach one leg and use it as a monopod is an excellent addition and the additional grip on this leg is nicely positioned and very comfortable.

The ability to move the main central point to a over the top arm for top down/lay flat is amazing! This creates much more potential, and having all this in ONE tripod is a bonus.

Overall this tripod feels very well built and feels like it will stand the test of time!

There are only three cons I can find!

- The included bag is not the greatest of materials and the added shoulder strap has plastic vs metal clips. However if your dedicated camera bag has space for a tripod this isn't an issue.

- The twist locks on each leg are plastic, however they do feel very strong and not flimsy at all. Being used to aluminium locks on the Manfrotto tripod I noticed this immediately.

- The springs that hold ratchet locks on each leg tight are a little flimsy, again being used to a different mechanism on the Manfrotto this bares no effect on quality and durability. If anything they are actually easier to release as the spring isn't extremely stiff!

Who would I recommend this to?

Anyone! This tripod is capable of meeting the needs of all photographers at all levels in my opinion! Whilst it may not be as rugged as some higher end brands, the fact remains that it is of very high quality and packed full of features. 10/10 for me.

Was looking for another tripod with a removable head so I can fit my Manfrotto fluid head onto. The tripod is super compact, lightweight and sturdy.

This tripod has allowed me to do overhead shots and amazingly it's holding my Panasonic GH5, but obviously you have to make sure you have the supporting leg in the same direction.

Overall I'm very happy with it and it's so versatile for many different scenarios.

Love the quality of this tripod also as it doubles up as a Monopod and is affordable

I bought this tripod to replace my top-quality Manfrotto, which has been a trusty companion for over 20 years of professional photography.

I needed a smaller, but still solid tripod to fit in the back box of my Honda 50, along with a large medium format camera, for local photo-trips. I measured the back box interior and noted the dimensions information that was given with the tripod, and it fits perfectly (see photo).

I was a bit dubious about the ball head holding my very heavy camera, so I replaced it with the heavy-duty pan and tilt head from the Manfrotto and it works perfectly. I've put the ball head from this one on the Manfrotto to hold a DSLR that I use for digitizing negs.

No, it's not as sold and robust as the Manfrotto (which cost 3 times as much), and that's to be expected. But it looks like it will do the job, and saves me from putting a really heavy tripod on my back when I go out on the bike!

All is great with exception to the description of monopod. The description states : "【Detachable Monopod】 It can be turned into a lightweight monopod or walking stick alone to make your photography more diverse. " To go along with this, the picture of the product shows the Monopod, Tripod folded, and Tripod open. The picture is deceiving as it shows the monopod alone along side the fully attached tripod. The description does not state that one of the tripod legs is to be removed to make the monopod. By seeing the pictures and reading the description, I thought the center column would be removed and used as the monopod. Thereby being a quicker change from Tripod to Monopod back to Tripod when needed.

I've been using this tri-pod for about a month and I like it a lot it. It isn't perfect but it works well. Its to large for a travel tripod or a hiking Tripod but with the protective case andhoulder strap I am able to carry it along with me and go to shoot locations. I also found it works great for macrophotography and product photography. Being able to move the tripod main shaft into a perpendicular position I was able to get the perfect straight down shot. It even converts into a mono pod. I haven't used this option yet since I had a decent monopod during my last hiking trip. I misplaced the monopod and I think its a goner. I plan on taking it on my next long trip in the late fall.The ball head screws that tighten down and lock it into place are ok but at the right angel it becomes difficult to hold in place. For large camera and lenses this could be an issue. The screw mount also makes a cracking sound if you tighten it down to much. So be careful.This is a tall and heavy tripod. Its great for windy days or shoot about the crowd's head. At full extension its almost 7 feet tall I think. When all the extensions are extended and stowed away. It uses a screw style locking system. They hold tight and I haven't had them loosen up while in use or transport.If you need a good tripod that can reach over the heads of the crowd, transform into monopod, or need a perpendicular tripod mount, then this is a great option. As always, I will update this review if anything changes.
