Goplus Rolling tray, 4.5 lb, magnets review

What you are getting

A rolling tool tray in high-density polypropylene, 102 mm (4 in) high, 520 × 419 mm (20.5 × 16.5 in), with four compartments — two large with dividers and two small — two powerful magnets in each small compartment, diamond texture on the bottoms, anti-slip handles and four 360° swivel casters. 55 lb capacity, 4.5 lb (2.0 kg) empty. $27.99.

It is the only item on this shelf that goes under the car

One hundred and two millimeters is the specification. Four inches of total height is what rolls under a car on axle stands beside you — the rest of this shelf stands up:

Item	Height
This tray	102 mm (4.02 in)
WoopJeem bucket dolly	94 mm (3.70 in) plus the bucket
DESEQPT cart	805 mm (31.7 in)
VEVOR cart	845 mm (33.3 in) packed
Arebos · Masko · Scheppach, published	not published

Goplus calls it a “tool creeper”, which is the right word: a creeper is the board a mechanic lies on, and this is the same idea carrying tools instead of a person. On this site’s axle stands and trolley jacks shelves the car goes up; this is what follows you underneath it.

Nothing else here does that, and nothing else needs to — a 20-inch tray is not a storage solution, it is the thing you load from the storage and take to the job.

And the magnets are what make a tray usable rather than annoying

“The upper and lower small compartments are each equipped with 2 powerful magnets at the bottom, which can hold tools and accessories in place for safe storage. The diamond texture of each compartment also avoids slipping.”

Four magnets in two compartments. On a tray that is pushed around a concrete floor and occasionally tipped, magnets are the difference between finding the bolts you took out and sweeping for them.

That is the one thing on this shelf that solves a specific, familiar failure. The published Masko and Arebos cabinets lock their drawers; the VEVOR cart hangs things on hooks; nothing else holds small steel parts down.

Diamond texture on the large compartments is the non-magnetic version of the same idea, and it works on plastic clips and rubber seals too.

Four compartments, split large and small

“2 large compartments and 2 small ones… Large compartment with dividers for flexible storage.”

That is the right split for taking a job’s worth of parts off a car: the large compartments take the bracket and the hose, the small magnetic ones take the fasteners. A single open tray mixes the two and loses the fasteners.

Fifty-five pounds, which is honest rather than impressive

55 lb is 25 kg, and it is the lowest capacity on this shelf by a wide margin — against 297 lb on the DESEQPT cart and 550 lb on the VEVOR cart.

It is also the right figure for what this is. Twenty-five kilos in a 20-inch tray 4 inches deep is a full tray, and the empty weight tells you the structure is honest about it: 4.5 lb (2.0 kg) of polypropylene carrying twelve times its own mass.

Compare the ratio on the rest of the shelf: the VEVOR cart’s 15.5 kg (34.2 lb) packed for 550 lb (250 kg) is sixteen times, the DESEQPT cart’s 9.3 kg (20.5 lb) for 297 lb (135 kg) is fifteen. All three are in the same range, which is a reason to take all three figures seriously.

But all four casters swivel, which the introduction warns about

“the 4,360° swivel casters make mobility a breeze.”

The introduction’s preference: “the castors — two fixed, two swivelling, with brakes that actually reach the floor.”

Four swivels wander: push the tray and it drifts sideways rather than tracking. On a cabinet crossing a workshop that is a nuisance; on a 20-inch tray being nudged two feet at a time under a car it is what you want, because a tray that tracks straight cannot be pulled sideways from a prone position.

So this is the one item on the shelf where four swivels is the correct answer rather than a compromise — and it is also the item with no brakes at all, which on a sloped driveway is a tray that keeps going.

No caster size is published, where the VEVOR cart publishes 5 inches. On a 102 mm tray the wheels are necessarily small, and small wheels stop at cables and floor joints.

Two kilograms, which is the other reason it works

“Weighing only 4.5 lbs, this moving caddy tray boasts great portability. The convenient handles with anti-slip texture allow for effortless carrying.”

It is the lightest item on this shelf by a factor of four, and the only one that is carried as a matter of course. The handles are published as part of that: a tray you can only push is a tray that stays on the floor.

What is not published

No drawers, slides, lock or worktop — the shelf’s stated criteria do not apply to a tray. No brakes on any caster. No caster size. No magnet pull strength, which on four magnets is the figure that would matter. No compartment dimensions or divider count. No warranty term, where the DESEQPT cart states one year.

At $27.99 it is the cheapest item on this shelf and the only one that fits under a car.
