It works great with my tripods

This product has a quality build and functions well. It is ideally suited to use in a studio environment as opposed to anything outside where dirt or debris might get into the bearings. That being said I like it all the same and have found it extremely useful.

Super smooth glide on this with large robust tires. It sadly doesn't get super wide so my video tripod needs to use it's center column to get height as it doesn't even allow one full extension on any of the legs to even go fully out.

It's super easy to install as there's quick release latches to extend it out and also to release the foot holder. The while system works very well.

Outside of the width being a little small, it's a great dolly.

Very happy with my item,thank you!
Fast delivery as usual!

We bought these to use on an art tripod, primarily for when sitting. They had the smallest width and best price. Have only been used indoors so far. They roll very well

In terms of build quality, it appears to have been fairly well-constructed; it is sturdy, and has a sleek finish.The dolly has a nice, smooth movement with the tripod in place, and its wheels have very secure locks. Once finished, it all folds down and packs away neatly into the handy storage bag, which you could then fit easily in a larger camera bag, or maybe a car boot.

In summary, I believe that this is a good value item.

Overall, the tripod truck makes a stable and high-quality impression. The workmanship is robust, and it can easily withstand even heavier stands with large cameras and lenses. The load capacity is more than adequate, so you don't have to worry about stability.

The rollers run smoothly and quietly, without annoying noises. This is particularly handy if you want to take quiet camera shots or simply need a mobile setup. If the car is found, it stands securely and does not move.

The trolley is adjustable and fits almost all photo and video stands. The stand legs can be clamped, keeping everything securely in place. For transport, it can be folded up and transported either via the integrated handle or with the included carrying bag. It therefore does not take up much space and is easy to store.

However, it is only conditionally suitable for light stands. The fixing mechanism is great with photo stands, but rather a hindrance with light stands. Since the lock is not via a side thumbscrew, but via an upward mechanism, this is in the way. Light stands can still be used, but only if you raise your legs steeper, which is of course at the expense of stability.

I had actually intended the car for my light stand with a large softbox, but now I mainly use it for my camera in the studio. It works better for this purpose.

Comes in a sturdy bag and opens in 30 seconds. The rollers run cleanly, the brakes work well and the material quality is also good.

The only problem is that the flick locks sit on TOP of the locks. If you now put a stand on it that has a too flat angle on the legs, you won't be able to get there smartly anymore because the Flick Locks lock is in the way. You have to make the angle steeper, which in turn reduces the floor space. Due to the increased weight, my light is still stable, which is okay. However, you could prevent yourself from locking the side simply. Because otherwise, there is nothing to complain about here, especially for the low price. K&F now really has some price-performance grenades on offer.

So: good part, but a star deduction due to the unfavorably placed closures.

PROS
-very stable once assembled and attached properly
-clever adjustability: legs go in and out, and tripod-foot clamps works very well
-wheels and pivot movement is very smooth
-solidly built (except for swivels)
-wheels of casters are solid
-custom bag
-good folding mechanism (they fold relatively small, and handle on top is very…handy).

CONS
-swivels bearings are open (not sealed, ball bearings are visible in the track), which is disappointing, as they will quickly pick up debris and dust in anything but the most clean environments.
-a bit heavy (not an issue, if you prepare for it)

NOTES
-I use this in a non-standard way, shooting “hyperlapses” (long distance motion timelapses), this and a tripod replaces long dolly tracks. This means I’m almost always outdoors, and the open bearings of the swivels is a real concern for me.
