Our Take
The Bowflex SelectTech 1090i is a single adjustable dumbbell that replaces 17 individual weights, ranging from 4 kg to 41 kg in increments of approximately 2 kg. Aimed at serious home gym users who want a wide lifting range without a full rack, it sits firmly in the premium segment and is sold as a single unit rather than a pair.
Key Features

Dial-select mechanism allows weight changes in seconds without plates or pins
Replaces up to 17 separate dumbbells per unit

Our Verdict
A strong choice for dedicated home trainers who lift heavy and need genuine range without sacrificing floor space. If you train with both light and heavy weights regularly, the investment is justifiable. Casual lifters or those on a tighter budget should consider a shorter-range adjustable dumbbell instead.
