What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Dreo Solaris Slim H3 (ALCI)
Real Homes is the only whitelisted outlet that hands-on tested this exact model (the review URL slug and specs — slim cylindrical form, H1/H2/H3 settings — confirm the Solaris Slim H3). The reviewer praised its quiet, consistent operation, slim styling, and simple controls with a useful eco pre-set, but warns it is underpowered for large or open-plan rooms and that the basic fan-only mode is not a reason to buy. No lab measurements were reported. (1 sourced review, 1 lab-tested.)
Praised: Quiet operation, equally quiet on lowest and highest settings; Slim, stylish, compact design that blends into modern interiors; Simple, intuitive touch/remote controls with useful eco pre-set.
Flagged: Underpowered for large or open-plan rooms; best as a personal heater; Fan-only mode is basic with no speed options; not worth buying for that alone.
De'Longhi EW7707CM ComfortTemp
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).
