## What reviewers say

**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.)

**CS-400** — Only one whitelisted tester, Pro Tool Reviews, published a genuine hands-on field test of the exact Echo CS-400 18-inch; other coverage (Consumer Reports, enthusiast blogs) fell off-whitelist and was excluded. Two professional tree-trimmers rated performance 9/10, praising the tool's perfect balance, easy two-pull i-30 starting and butter-smooth cutting through a palm stump, decking and small trees. The flags are loud ~107 dB full-throttle operation that demands hearing protection, a Value score of only 7/10 on price, and the tester's own caveat that long-term reliability was not assessed. (1 sourced review.)
