What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
DeWalt DCHT820B 20V MAX 22" Cordless Hedge Trimmer
Only one whitelisted tester, Pro Tool Reviews, published coverage of the DeWalt DCHT820 (the 20V MAX 22-inch model); it is a short overview piece with no lab measurements. It praises the low 7.8-lb bare weight and calls the tool capable for maintenance trimming, but flags the 2800 SPM speed and 3/4-inch cut capacity as tame versus professional rivals and notes it is a brushed, limited-capacity model. The verdict rests on a single reviewer's qualitative assessment. (1 sourced review.)
Praised: Low working weight makes it easy to maneuver; Capable of regular maintenance cuts on neglected hedges.
Flagged: 2800 SPM speed and 3/4-inch cut capacity are tame for professional use; Brushed motor and limited capacity versus premium/pro competitors.
