## What reviewers say

**Bosch CS5 15-Amp 7-1/4 in. Left-Blade Corded Circular Saw** — Only one whitelisted tester, Pro Tool Reviews, covers the Bosch CS5, and it is a brief 2010 first-look preview rather than a hands-on lab test, so no independently measured numbers exist. It praises the left-blade line of sight and calls the 15-amp saw one of the best values; no critical testing or negatives are available. (1 sourced review.)

**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.)
