What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
FLEXVOLT DCCS670
Only one whitelisted tester, Pro Tool Reviews, hands-on tested the DeWalt DCCS670. In its 8-saw shootout it placed 4th overall, praised as a fast, well-balanced cutter (5.93s through 8-inch pine) with wide, comfortable handles, but dinged for a side cover that clogs with chips and flimsy plastic bucking spikes. (1 sourced review, 1 lab-tested.)
Praised: Fast, well-balanced cutter — one of three saws to break the 6-second mark (5.93s avg) on an 8-inch pine log, 3rd in cutting speed; Wide front and rear handles feel secure in the hand, especially the full-wrap rubber rear grip; Strong feature set: easiest tool-free adjustment, coast-down chain brake, and a glove-friendly quarter-turn oil cap with the best oil-pouring access tested.
Flagged: Enclosed side cover lets chips pile up above the tension knob and clog the saw, spraying chips out the front and impairing visibility; Small plastic bucking spikes weaken leverage on vertical bucking cuts; Idiosyncrasies keep it out of the top tier — ranked 4th of 8 overall.
Pro 80V 18" Chainsaw
Only one whitelisted tester, Pro Tool Reviews, has a hands-on field review of this exact 18-inch 80V Pro model (GCS80420). It scored 8.5/10, praised for gas-like cutting power and rugged build, with short run-time the main knock. No tester-measured benchmark numbers were published (only manufacturer specs). (1 sourced review, 1 lab-tested.)
Praised: Gas-like cutting power; the 18-inch bar cleanly sliced 16-inch oak trunks; Rugged, gas-saw build feel — metal wrap-around handle and steel bucking spikes; Near-instant on-power versus competitors' start delay, plus quieter operation than gas.
Flagged: Short run-time on the 2.0Ah battery; needs spare packs for larger jobs; Heavy and hefty — not an ultralight in-tree saw; Can stall if pushed too hard into thick trunks.
