## What reviewers say

**Ridgid R8654B 18V OCTANE Brushless Cordless 7-1/4 in. Circular Saw** — Only one whitelisted tester, Pro Tool Reviews, published a hands-on head-to-head review of the exact R8654B; no other whitelisted hands-on reviews were found. Their verdict: a solid brushless upgrade over Ridgid's Gen5X with excellent blade sightlines and shoe glide, but middling raw power (lowest of three power tiers in their test), a guard that hangs on thin cuts, and heavy weight. (1 sourced review.)

**Skilsaw SPT77WML-01 15-Amp 7-1/4 in. Lightweight Magnesium Worm Drive Circular Saw** — Only one whitelisted tester—Pro Tool Reviews—had accessible review prose for this exact model, naming the Skilsaw SPT77WML its best corded worm-drive circular saw for its 77-series 15-amp power and lightweight magnesium build. No other whitelisted source with accessible measurements was available, so no cross-source comparison exists. (1 sourced review.)
