Buy the Nuobell 580 if 80 lb covers your heavy work and you train the full range down to 5 lb on the same dumbbell. Buy the 1090 if you specifically need the last 10 lb to 90 and prefer a dial, accepting a 10 lb floor that makes it a heavy-only tool. Most homes are better served by the Nuobell's full range than the 1090's extra ceiling.
Range shape
The Nuobell runs 5 to 80 lb. The 1090 runs 10 to 90 lb. Both step in 5 lb increments. Read that as two different tools: the Nuobell is a complete dumbbell, the 1090 is a heavy specialist that still needs a light partner for warm-ups and isolation work.
Mechanism and materials
Twist selection in a machined cradle with a knurled steel handle, against dial selection in a molded tray with plastic in the selector path. Owner feedback on feel is not close. Owner feedback on price is not close either, in the opposite direction.

FAQ
Questions, answered straight
Which holds value better?
Steel-heavy designs with simple wear paths tend to age gracefully in owner feedback, and the Nuobell's construction points that way. Neither is an investment; buy the one whose range shape matches your training this year.
