Every number below is copied from a manufacturer page or official sheet and carries an as-of date of 2026-10-14 on the product records. If a field is blank on the maker’s page, it stays blank here.

PowerBlock describes the PowerBlock Elite EXP as: Selector-pin expandable pair published at 5–90 lb (2.3–40.8 kg) per hand with 2.5/5 lb micro-weight increments and a 5-year residential warranty. PowerBlock's official Elite EXP page lists a 2.3–40.8 kg (5–90 lb) range with Stage 1 at 50 lb, Stage 2 at 70 lb, and Stage 3 at 90 lb per hand. Two 2.5 lb (1.1 kg) micro weights per handle enable 2.5 and 5 lb increments; dimensions are 41.3 × 15.2 × 15.2 cm with a magnetic selector pin. Warranty is a 5-year limited residential warranty. The US product URL returned 404; specs are from the live AU manufacturer page and the June 2025 Elite EXP owner's manual.

Who the NÜOBELL 580 is for, in our reading of the spec sheet: Lifters who want a published 5–80 lb twist-handle pair that replaces 16 traditional dumbbell pairs. Skip it when needs increments finer than 5 lb or a starting weight below 5 lb.

Who the PowerBlock Elite EXP is for: Lifters who want a published Stage 1 5–50 lb set that expands to 70 lb then 90 lb with official Stage 2 and Stage 3 kits. Skip it when needs Elite USA or Pro-series attachments, which PowerBlock states are not compatible with Elite EXP.

If ceiling height is the constraint, prefer the shorter published frame and then run Will-It-Fit with your ceiling, your height, and the exercise. HAJEX’s standing-press rule of thumb is height × 1.33 plus about 9 in for full-size plates. A rack that “fits the room” on assembled height can still fail a pull-up if there is not about a foot above the bar.

This page does not say either product was used, assembled, or worn-in by FitScout. Sources are the manufacturer URLs on each spec row. If a maker updates a dimension after 2026-10-14, the as-of date is the tell.
