What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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.)
Praised: Electronic vibration control makes a world of difference; as smooth as pneumatic Dynabrade sanders over a full day with no hand numbness; Powerful Multi-Jetstream dust extraction — suction strong enough to stick the sander to a vertical surface; Instant pad brake stops the pad the moment you power off, so you can set it down without leaving swirl scratches.
Flagged: No variable-speed paddle like a pneumatic sander — speed adjusts only via a dial; Added weight versus a pneumatic sander is noticeable on vertical surfaces.
DeWalt DWE6421K 5 in. Single Speed Random Orbit Sander Kit

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.
