## What reviewers say

**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.)
