What I like about it? is it's extremely light. The fasteners are solid. There is a monopod attachment,but why I bought this is the center column locks at 90° for some nice overhead shots.

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.
Negative
- 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!

Exactly what I was looking for and I like it better than my expensive Manfrotto like model I have.

The 63-Inch Monopod in Black has truly impressed me with its exceptional stability, lightweight design, and effective image stabilization. Whether capturing dynamic scenes or shooting in challenging conditions, the monopod provides a reliable support system, ensuring my photos remain sharp and clear. Its lightweight construction adds to the overall convenience, making it a go-to accessory for on-the-go photographers. The integrated image stabilization is a standout feature, significantly reducing vibrations and enhancing the quality of my shots. Setting up the monopod is a breeze, and its durable build instills confidence in its long-term performance. In summary, this monopod is a versatile and reliable tool that exceeds expectations, making it a valuable addition to any photographer's gear arsenal.

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.

K&F Concept TM2515M1's tripod appears to be lightweight, sturdy, and strong. Adjustments are relatively smooth. Height is more than I needed. Really great tripod except for one item, which has triggered my decision to return it: the Monopod leg is about 1/4" - 1/2" shorter than the other 2 fixed legs, so when you fully extend all 3 legs, the tripod is slightly tilted and not level due to the monopod leg being shorter. Of course you can adjust the difference out, but it takes a bit more time during initial setup. Would have been perfect if all 3 legs where the exact length at full extension.In addition, the latch/hinge for the monopod side appeared to be defective on the unit I received as well. It felt "looser" compared to the other 2 fixed legs.

Decent fixed nd filter
