Review consensus · sourced & dated

What reviewers say about the 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.

Based on 1 review · 2017-10-12

Tested by Pro Tool Reviews

Consistently praised

  • Brushless motor upgrade for longer runtime, more power, and longer motor life
  • 26% larger cut capacity from the full-size 7-1/4-inch blade (up from 6-1/2-inch)
  • LED cut-line light, dust blower, and left-mount blade improve cut-line visibility
  • Still cheaper than comparable circular saws; a value pick for existing One+ owners

Commonly flagged

  • Price roughly doubles that of the previous P507 model
  • Still lacks a rafter hook
  • Left-mount blade is less convenient for left-handed users

Where reviewers disagree No cross-source comparison is possible: only one whitelisted outlet (Pro Tool Reviews) covers the exact P508, and only as a pre-launch preview with no hands-on measurements. There is no second surviving source to agree or disagree with.

Pro Tool Reviews hands-on ·

The Ryobi P508 looks like a better product all around, though to be fair, the P507 is a couple years older.
It is, however, still missing the rafter hook.
As a tool for DIYers and maintenance crews already running the One+ system, this purchase should be a no-brainer.
