Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Reviewed (USA Today) is the only whitelisted tester with a hands-on lab result for this exact model. The same lab test (tester Jon Chan) appears in its US edition (°F) and Canada edition (°C). It measured a modest max output (~83°F / ~28°C) and only a 3-degree room-temperature rise over an hour, ranking the EW7707CM best for basements and keeping pipes above freezing but 'not very powerful' as a personal heater. (2 sourced reviews, 2 lab-tested.)
Praised: Energy-efficient; best pick for basements and keeping pipes above freezing; Called a solid performer in lab testing.
Flagged: Not very powerful as a personal/spot heater — raised the room only ~3 degrees in an hour; Low max output (~83°F / ~28°C); not as good a personal heater as the DeLonghi HMP1500 (ranked 3rd in the Canada test).
