Our verdict

A light iron adjustable dumbbell kit at just under 12 kilograms total, worth it mainly as a starter set rather than a heavy-duty pair.

Overview

This adjustable dumbbell kit is made of iron, totals 11.59 kilograms across the set, and ships as 21 separate pieces covering plates, handles and collars.

With 21 pieces making up roughly 25.5 pounds total, this reads as an entry-level starter kit rather than a heavy pair, since a single adjustable dumbbell in the 20 to 40 pound range already approaches that combined weight. Worth checking the piece breakdown against your target final weight before buying.

  • 11.59 kilogram total weight
  • 21 pieces in the set
  • Adjustable plate-and-collar design

Who it's for

Suits someone starting out with adjustable dumbbells at a light total weight, more likely built as one dumbbell from plates than a matched pair. Not suited to lifters needing heavier loads without buying additional plates separately.

Pros and cons

Pros
  • 21-piece set allows building different weight combinations
Cons
  • Total 11.59 kilograms, about 25.5 pounds, is light for a full dumbbell set
  • Generic brand naming makes it hard to cross-check against other buyer feedback

Performance notes

Iron plate-and-handle sets like this rely on threaded collars to lock plates in place. With 21 pieces total, assembling and swapping weight increments takes more handling than a dial-adjust dumbbell, in exchange for a lower cost per pound.
