I have a large Manfrotto backpack for long trips, but for daily work it is too bulky. it also has a compartment for a notebook and a bottom for the rain, all in the ideal size.

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!

Overall ok. Hard to tighten upper connectors to camera and to stop all movements. Needs weight to stabilize more. Manfrotto overall better tripod for $. Manfrotto packs to a smaller space and case.

Sure, extended to its full height outdoors, this isn't the sturdiest place to mount a camera. If you so much as breathe heavy on it, your camera will shake a bit. But for a commercial photography setting, this tripod has become a valuable part of my real estate kit. I have been using the Manfrotto XPRO series for years, and this tripod raises the functionality bar a whole step with the ability to invert the center column and shoot stable all the way to ground-level and even below if you need to shoot in a hole for some reason. I will still use my heavy aluminum X-PRO's for those windy days or when I'm sporting huge, heavy lenses like the Sigma150-600mm; but indoors and calm-air exteriors I've been shooting almost exclusively with this tripod in the week and a half since it arrived and I really like it. If it fails me at some point, I'll update.

If K&F were to make a beefier version of this model, I would try to be the first to order it. Double-thick legs and heavier locks plus the 8-foot reach and to-the-ground shooting would put the Manfrotto line to shame.

Great, holds the camera steady and doubles as a walking stick.

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!
