Big weight jumps rather than small progressive steps

NordicTrack 55 Lb. Select-A-Weight Adjustable Dumbbells (NAMSDB20)
Lifters happy to start at ten pounds per hand
A pair of selector dumbbells giving 15 settings per hand between 10 and 55 pounds, with moulded storage trays included and a matching stand sold separately. The 10 pound handle bar sets the floor of the range, and NordicTrack does not publish an owner's manual for this model online.
Published specifications
- Maker page: model NAMSDB20, 15 weight adjustments per dumbbell
- Maker page: adjusts from 10 lb to 55 lb; 10 lb handle bars

Strengths
- Fifteen settings per hand with a single selection system

- NordicTrack publishes the exact model number on its own page
Caveats
- Nothing lighter than 10 pounds, because the handle bar alone weighs that
