## What reviewers say

Two whitelisted testers cover the DWE6421K, but only Reviewed hands-on-tested it, naming it Best Overall for stripping paint in about three minutes versus roughly five for rivals. It praises the powerful 3-amp motor, comfort and decent dust collection, while flagging single-speed operation and that the tool jumps and pulls. Pro Tool Reviews is a spec preview, not benchmarked. (Based on 2 reviews, 1 lab-tested, 2015-10-28–2022-04-27.)

Praised: Fast, powerful 3-amp motor; fastest paint removal in the test (~3 min); Comfortable to hold in multiple positions; Decent/quality dust collection, especially with a shop vac.
Flagged: Single speed only; Jumps and pulls; harder to control than rivals.
Disagreement: No genuine cross-source disagreement exists because only Reviewed benchmarked the sander; Pro Tool Reviews merely previewed manufacturer specs. Reviewed itself frames the strong 3-amp power as double-edged: it enables the fastest material removal but is also the direct cause of the control/jumping complaint.
