An adjustable dumbbell pair that swaps between several weights instead of needing a rack of fixed ones. The listing is unclear whether the stated weight is per dumbbell or for the pair, so settle that before ordering.

Overview
Switching between five weight settings is the point of this FLYBIRD pair, which packs several dumbbell weights into two adjustable units. The body and the handle are both metal.
Adjustable pairs replace a shelf of fixed dumbbells with two compact units, which matters in a spare room. The title advertises two weight options, and the page does not make clear which version it covers.
Who it's for
Home trainers who vary their loads from exercise to exercise get the most from an adjustable pair. A strength athlete who needs very heavy loads, or who wants to know the exact weight steps, will find the details thin.
Pros and cons
- Several weights in one pair
- Metal body and handle
- Two dumbbells in the set
- Quick change claimed in the title
- Weight option unclear in this listing
- Weight increments not listed
- No warranty details given
Performance notes
Load changes by adjusting each dumbbell, so how smooth the change feels depends on a mechanism the listing never describes. A metal handle at the stated diameter sets the grip feel, and thicker handles ask more of the hands. Overall length and width are listed, which helps judge storage space.
