## What reviewers say

**Festool ETS EC 150/5 EQ** — One whitelisted hands-on review — Pro Tool Reviews' month-long shop test — covers this exact model (the reviewer explicitly puts the ETS EC 150/5 through real furniture work). It scores the tool 9.8/10, praising electronic vibration control, smoothness rivaling pneumatic Dynabrade sanders, powerful Multi-Jetstream dust extraction and the instant pad brake, faulting only the absence of a variable-speed paddle and noticeable added weight on vertical surfaces. No lab measurements were reported. (1 sourced review.)

**DeWalt DWE6421K 5 in. Single Speed Random Orbit Sander Kit** — 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. (2 sourced reviews.)
