NEEWER SD001 dolly, 200 g, wheels set from -45 to +45 degrees review
A 200 g pocket dolly at 37 €, running on rubber wheels that turn through 90 degrees to trace a circle — with a ball head in the box and a warning against telephoto lenses.
The bottom line Two hundred grams, fully dimensioned, with wheels that turn to trace a circle and a ball head in the box: at 37 € this is the most honest object on the shelf about what it is and is not for. It has no rail, no drag control and no load figure — and it says outright that a telephoto does not belong on it.
On the listing
Five bullets. An articulating manual dolly moving in straight lines or in a circle, with wheels adjustable from minus 45 to plus 45 degrees to control the panoramic range for subjects of different sizes, working with mirrorless cameras, mini camcorders, phones and action cameras; wheels padded with soft rubber rings running quietly and smoothly on floors, tables and camera sliders, with a note that it is not suitable for telephoto lenses; an adjustable ball head with 360 degrees of rotation and 90 of tilt on a 1/4 inch screw, listing DJI Osmo and Insta360 models; a rotating phone holder for vertical or horizontal framing with a cold shoe for a microphone or fill light; and a compact body of 100 by 84 by 20 mm weighing 200 g in black aluminium.
Wheels that turn, and the shot that follows
Minus forty-five to plus forty-five degrees. Straight, and the camera drifts past a subject; angled, and it walks around one at a fixed radius. The circular move is the reason to own a dolly rather than a rail, and it is published as an angle range rather than claimed as a feature.
Two hundred grams, and every dimension
A hundred by eighty-four by twenty millimetres. It is the only object on this shelf whose size and weight are both published, which for something that lives in a bag beside the camera is the pair that decides whether it comes along.
The warning is the load figure
No kilograms, and a sentence instead: not for telephoto lenses. On a dolly the failure is tipping and shake, not collapse — and a lens that reaches forward causes both regardless of what it weighs.
What a hand has to supply
No drag control. The evenness of the move is the evenness of the push, and on a table that is a matter of practice rather than equipment.

What it does well, and what it gives up
Strengths
200 g and 100 by 84 by 20 mm published — the only fully measured object on this shelf
Wheels that set from minus 45 to plus 45 degrees, so the dolly runs straight or traces a circle around a subject
A ball head, a phone holder and a cold shoe included at 37 €
Compromises
No declared load, and an explicit warning that it is not for telephoto lenses
No rail, so the smoothness of the move depends entirely on the surface and the hand
No drag control, which is what separates a usable move from a discarded one
Specifications
Rail length
None — there is no rail. The first bullet describes an articulating manual dolly that moves on the floor, a table or a camera slider, so the track is whatever surface it is set on. It can also run along another slider’s rail, which is the one case where a length would apply and it belongs to the other product
Actual travel
Unlimited in principle, and unbounded in practice: the dolly travels as far as the surface allows. The hub above compares rail length against travel because a carriage runs out of track; this one runs out of table
Declared load
Not published as a figure, and the second bullet publishes something better than silence — a limit in words: not suitable for telephoto lenses. That is a warning about leverage rather than mass, and on a 200 g dolly it is the honest form of the statement
Bearing type
Four wheels padded with soft rubber rings, in the second bullet, credited with quiet and smooth running on floors, tables and slider rails. Rubber on a hard surface is what keeps a dolly silent enough to record sound beside
Drag control
None published. The movement is by hand, and no adjustable resistance is named — so the smoothness of a shot is entirely in the push
Motorisation
None. The first bullet calls it a manual dolly; the motorised alternatives on this shelf cost three and nine times as much
Mounting points
A 1/4 inch screw carrying an adjustable ball head with 360 degrees of pan and 90 of tilt, in the third bullet, with a rotating phone holder and a cold shoe for a microphone or a small light in the fourth. Compatible devices are named model by model, from DJI Osmo and Insta360 units to current iPhone and Galaxy handsets
Weight
200 g, in the fifth bullet, with the full dimensions: 100 by 84 by 20 mm. It is the only page on this shelf to publish both

What people ask before they commit
How does a dolly trace a circle?
By turning its wheels. The first bullet gives the range — minus 45 to plus 45 degrees — and the geometry follows: wheels angled inward describe an arc rather than a line, so pushing the dolly walks the camera around a subject at a fixed radius. It is the move that makes a small object look filmed rather than photographed, and no rail can do it.
Why warn against telephoto lenses?
Because of leverage and amplification, not weight. A long lens puts its mass far forward of the wheels, which tips a 200 g dolly, and it magnifies every ripple in the surface into visible shake. The second bullet states the limit plainly rather than publishing a load figure that would not describe the real failure.
Does it run on a slider rail?
The first and second bullets both say so: floors, tables and camera sliders. On a rail the wheels are guided and the move is straighter than on a free surface — so the dolly and a rail are complementary rather than alternatives, which is unusual on a shelf where the other three replace each other.
A motorised rail slider · stepless speed from 0.1 to 5 cm per second · declared load 4 kg horizontally and 2.5 kg vertically — the only page here to publish both · brushless motor described as near-silent · full button control without an app · custom motion paths set by Dot AB, manually or through the app · no rail length published in the bullets · no travel published · no weight published · no mounting points published
The only support here that publishes a horizontal AND a vertical load — 4 kg and 2.5 kg — with stepless speed from 0.1 to 5 cm per second, at 319 €.
Best for: Interview and product work where the move has to be repeatable, silent and usable on an incline with a camera worth protecting.
A motorised wheeled dolly rather than a rail · three speeds, 2.4, 2.6 and 2.8 cm per second · reversible direction · wheel angle adjustable through 180 degrees for straight or circular paths · declared load 3 kg · wireless remote effective to 6 m · 1/4 to 3/8 inch convertible screw with a ball head supplied · 1800 mAh cell giving up to 6 hours · plastic body · no weight published
Three published speeds in centimetres per second, a 3 kg load and six hours of battery for 108 € — a motorised dolly whose every figure is stated except its own weight.
Best for: Time-lapse and slow product moves on a smooth floor or table, where a hands-off motorised drift matters more than a guided rail.
A focusing rail rather than a travelling slider · movement in four directions, left, right, forward and back · rack-and-pinion drive with a precision scale · 1/4 inch mounting screw · aluminium alloy · no rail length published · no travel published · no declared load published · no motorisation · no weight published
A 28 € two-axis macro focusing rail, not a travelling slider: rack and pinion, a precision scale, four directions of movement — and not one dimension published.
Best for: Macro work on a tripod, where focus is set by moving the camera rather than the lens and the position has to be repeatable.
