What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Concept2 RowErg
Both whitelisted hands-on testers — Wirecutter and Garage Gym Reviews — rank the Concept2 RowErg the best rower they've tested. Shared praise: a sturdy, commercial-grade build that doesn't feel cheap, clear and reliably accurate PM5 metrics, and strong durability with easy parts replacement. Shared gripe: the roughly $1,000 price and a simple monitor with basic built-in programming. Wirecutter alone credits the secure, non-slip foot holsters and flags loud operation plus having to stop mid-workout to change resistance; Garage Gym Reviews alone notes the seat hardens over long-term use. Noise is the one clear disagreement. (2 sourced reviews, 2 lab-tested.)
Praised: Best rower / best workout experience of all machines tested; Sturdy, commercial-grade build that doesn't feel cheap; PM5 monitor metrics are clear and reliably accurate.
Flagged: Expensive at roughly $1,000; Simple monitor with minimal built-in interactive programming; Loud flywheel — noisiest rower Wirecutter tested.
