[Carbon Fiber] Very original product suitable for a standard monopode with an unexpensive thread adapter

[3/8"-16 Male] I wanted a compact tripod for an upcoming overseas trip and this looked like a good fit. I already have two Induro tripods and heads but they are still bulky for airline travel, hiking and city vistas. This Field Optics model is surprisingly sturdy and keeps my DSLR very stable. The lower overall height is fine as I intend to use it low down for waterfalls, landscapes and city lights. The reverse folding center section makes it very compact so its easy to drop into a camera shoulder bag. I added a skinny ballhead to keep the overall weight down. Very happy; lets see how it performs next month in the UK.

[Carbon Fiber] Precision engineered with solid feel, yet very, very light. I generally use the larger FPH-200 pan head with the 85mm spotting scope for range duty, but this ball head is a perfect complement to my 55mm spotter for backcountry glassing.
Another top tier product from Field Optics Research.

[Twist Lock] Yes, a little pricey, but very good. I have not been able to find anything else that really competes with these.

[Yes] I need a rock-solid tripod. I typically zoom to between 2000 mm and 3000 mm to shoot bird portraits. At this magnification any vibration in the tripod results in soft photos. I purchased the FT-6852A because it was designed specifically for extreme strength and stability as an optics platform for long lens photography and similar activities. I have found that it is indeed very sturdy and damps vibration fast. With it, I routinely take tack sharp photos at 3000 mm equivalent. Since I pan the head between shots, I added a FLM leveling base to the top of the center column (under my pan/tilt head). This addition does not affect the features of the center column. The center column (being both separable and reversible) provides two ways to shoot from ground level; and, (being 32 mm in diameter) it also provides a way to quickly change the tripod height
without degrading image sharpness. Finally, the tripod comes with a nice padded case that holds the tripod with both my leveling base and pan/tilt head attached.My photos have definitely improved since I bought the FT-6852A. I can transport it easily, set it up quickly, and take sharp photos at very high magnification.

[Twist Lock] Sturdy build with super smooth adjustments. Currently using with a Sony a6300 and 12mm on a slider for indoor fitness shoots. The ball head mounts quickly and setting up the camera is a breeze.

[3/8"-16 Male] I haven't put this through the wringer yet, but I have initial impressions.

Strengths:
Light
Strong
Smooth panning
Smooth plate release
Bubble levels

Potential weaknesses:
The pan tension screw seems to be an all or nothing deal. The panning is smooth and has a fair bit of resistance so the screw really only serves to lock the panning. Maybe the panning will become less resistant over time

The 'ratcheting' mechanism for tightening the ball is a great feature since you aren't limited by turning once right or left then running out of room to turn. IMO, it would be nice if each turn added resistance more slowly so fine tuning the tension was easier

[Carbon Fiber] I needed a light, reliable and high-quality ball head for my tripod. I found it here. But I could not buy it, delivery is not carried out in my country. I bought it elsewhere. Loved it. Recommend.

[3/8"-16 Male] I bought this to replace my 3-legged thing I bought a year ago.  

The 3-legged thing tripod has lost several components, including the weight hook under the center column. The worst is the center column can be accidentally pulled off and can never be put back properly again.

I choose this model for its light weight, which is barely over 2 lbs. Also, it has an excellent price.

The first impression when opened the box is its surprising robust construction, very sturdy. 

I knew it is short, that I planned to use it with waist level finder on my medium format camera and the angle finder on my Leica. It is what I wanted, but after opened it, I think a little taller could be better.

Its weight is slightly heavier than I thought. It does match the spec, but I just realized that my 3-legged thing is about 1 pound lighter. So, if you want something really light weight, get the carbon fiber version. And better yet, get a taller model from this manufacturer.

Overall, I am very happy about this manufacturer for its quality. ButI recommend to get the taller and carbon fiber version. 

No, I would not return it or make exchange. It is more than good enough for me.
