What to know before buying
Listing details to confirm
The listing conflicts on construction: details say cast iron, while a feature says steel and the description specifies powder-coated cast-iron discs with galvanized iron rods. It also describes an included 30 cm bar but does not consistently state its length, gives an overall weight of 30 kg, and lists dimensions of 90L x 16W centimetres. Confirm the selected listing's materials, dimensions and included bar before buying. The description also recommends applying rust-proof oil before use and storing the dumbbells high, and cautions that children must not play with the handling.
Who is it for?
A good fit for
- Home strength training where adjustable dumbbells and a connected barbell configuration are useful.
- Buyers who want plate-based weight changes using the listed 2.5 kg and 1.25 kg plates.
Less suited to
- Buyers who need confirmed compatibility with other 1-inch plates, as customer feedback reports fit issues.
- Buyers who require an unambiguous materials and dimensions specification without checking the listing.
