Independent testing
How much independent testing exists for each chainsaw
Of the 10 chainsaws 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 |
|---|---|---|---|
| FLEXVOLT DCCS670 | 1 | 2 | 1 |
| CS-400 | 1 | 1 | 1 |
| M18 FUEL 16" Chainsaw | 1 | 1 | 1 |
| 455 Rancher | 0 | 0 | 1 |
| CS1500 | 0 | 0 | 1 |
| MS 271 Farm Boss | 0 | 0 | 1 |
| MSA 220 C-B | 0 | 0 | 1 |
| Power+ CS1804 | 0 | 0 | 1 |
| Pro 80V 18" Chainsaw | 0 | 0 | 1 |
| XCU04 (18V X2 LXT) | 0 | 0 | 1 |
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 Chainsaws buying guide and the reviewers we cite.
