Independent testing
How much independent testing exists for each rowing machine
Of the 7 rowing machines we track, 3 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| Concept2 RowErg | 2 | 2 | 2 |
| NordicTrack RW900 | 1 | 3 | 3 |
| WaterRower Original Series (Oak) | 1 | 1 | 3 |
| Aviron Strong Series | 0 | 0 | 2 |
| Ergatta Luxe | 0 | 0 | 1 |
| Hydrow Origin (formerly Hydrow Pro) | 0 | 0 | 4 |
| Hydrow Wave | 0 | 0 | 4 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Rowing Machines buying guide and the reviewers we cite.
