What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
XCU04 (18V X2 LXT)
Only one whitelisted outlet, Pro Tool Reviews, covers the exact XCU04, and its piece is a spec-driven first look rather than a lab test, with no measured cut times or noise. It frames the 36V dual-18V saw as a quiet, low-maintenance gas alternative weighing 11.5 lbs. (1 sourced review.)
Praised: Positioned as a quiet, emission-free alternative with power rivaling a 32cc gas chainsaw; Manageable 11.5 lb weight even with both 18V batteries attached; Lower maintenance than gas: no spark plug, engine oil, or air filter.
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.
