One pair, or fifteen — and the difference is a mechanism · review
A two-in-one set sold across a 15 to 40 kg range, with a published 400 mm connecting tube and a stated 15 mm of foam padding on it. The contents list is complete; the plate breakdown is not.
The bottom line The contents list is its strength and the plate list is its gap. A published 400 mm connector with 15 mm of padding is more detail than most competitors give about the part a hand actually touches, but without a plate breakdown the smallest usable step — the single most important figure on an adjustable set — cannot be read from the listing at all.
A two-in-one arrangement: two metal dumbbell bars that join with a 400 mm connecting tube to make a short barbell. The tube carries 15 mm of foam padding, which the maker states directly.
Four double safety collars are supplied. The plates are described as cement-and-sand filled under a floor-friendly plastic coating, and the plates are said to be notched externally so they do not roll.
The set is sold across a 15 to 40 kg range.
There is no plate breakdown. On an adjustable set, the list of denominations is what decides whether a range can be stepped through, and it is the first thing this site looks for.
Without it, the smallest available change is unknown until the box is open — and a 40 kg set built from four 5 kg plates is a different tool from a 40 kg set built from sixteen smaller ones.
Not much about load, and something real about use. A connecting tube is where a hand sits during the barbell movements, and a published padding thickness is a genuine measurement about that contact.
It is also an unusual thing for a maker at this price to publish at all, and that is worth recording.
15 to 40 kg spans several versions of the product rather than an adjustment on one. Which one arrives follows from what is ordered, and the listing does not tie a plate list to each version — which is the same gap as above, seen from the other side.
From 37 € to 49 € across the German, French, Italian and Spanish Amazon stores, on the one reading this page rests on.
The British Amazon store carries it too, priced in local currency — which the euro range above leaves out on purpose.
The American Amazon store returned nothing at all, so the buy button there opens a search rather than an empty page.
These figures are what Keepa returned on the day this page was last written. Stock and prices move without notice.

It is the span of versions the maker sells under this name rather than an adjustment range on one product. Which plates arrive depends on the version ordered, and the listing does not publish a breakdown for each.
The maker states 15 mm of foam padding on the connecting tube. It is a real published dimension about the grip surface rather than about the load, and it is the kind of figure this shelf rarely bothers with.
The maker describes them as four double safety collars, which is its own term for the closure and not a published measurement. The page reports the description as the maker’s word rather than translating it into a figure.

44 cm bars, 40 cm connector, 50 kg per bar
A 20 kg pair that converts to a barbell with a supplied 40 cm connecting tube. Bar length, connector length and a per-bar load figure are all published, which is three more figures than most of this shelf gives.
Best for: A first purchase where one set has to be both dumbbells and a short barbell
12 plates, 4 star collars, cement fill
A 40 kg spinlock pair sold on floor protection as much as on load: cement-filled plastic plates, cross-knurled handles and four star collars. The plates are the reason it is cheap and the reason a bar fills up early.
Best for: A first pair where the floor matters and the total never needs to be high
16 plates in four steps, 47 cm bars
A 30 kg spinlock pair whose useful figure is its plate list: sixteen plates in four denominations, on two published 47 cm bars. The 1.25 kg smallest step is finer than most sets at this price.
Best for: Someone who wants small increments rather than a high ceiling
