## What reviewers say

**WaterRower Original Series (Oak)** — Three whitelisted testers (Wirecutter, BarBend, Garage Gym Reviews) hands-on reviewed the WaterRower Original/Classic series and broadly recommend it as a quiet, beautiful, sturdy water rower. All praise its meditative whooshing sound and compact vertical storage; all flag a bare-bones monitor with paid tech add-ons (no built-in Bluetooth). Wirecutter warns its distance/time readouts run optimistically fast. GGR's spec card lists an Oak frame with the S4 monitor while its body copy calls the unit the 'WaterRower Natural' — the same machine mechanically. (3 sourced reviews.)
