## What reviewers say

**DeWalt DCS570B 20V MAX XR Brushless 7-1/4 in. Circular Saw** — One whitelisted hands-on source (Pro Tool Reviews, 8.1/10) was verified for this exact saw (the review's spec table names Model DCS570B, the bare tool). Over several weeks of cutting plywood, rough lumber, PT and MDF, the reviewer calls the DCS570 a legitimate corded-sidewinder replacement with smooth bevel detents and a fast electronic blade brake, and standout value, while flagging the push-in trigger safety and the absent rafter hook. (1 sourced review.)

**Ryobi P508 ONE+ 18V Brushless 7-1/4 in. Cordless Circular Saw** — Only one whitelisted source covers the exact P508: a 2017 pre-launch preview from Pro Tool Reviews, not a hands-on lab test, so no measured results exist. It praises the brushless motor and 26% larger 7-1/4-inch cut capacity as clear upgrades, but flags the doubled price and still-missing rafter hook. (1 sourced review.)
