## What reviewers say

**Milwaukee M18 FUEL 2880-20 4-1/2 in./5 in. Grinder Paddle Switch No-Lock (Tool Only)** — Only one whitelisted tester, Pro Tool Reviews, covers the exact 2880-20, and only inside a Milwaukee lineup comparison rather than a standalone bench test. Editors endorse its runtime and safer paddle-switch design, but every performance figure (135 rebar cuts, 11A, 8,500 RPM, $199) is Milwaukee's own claim, not independently measured.
