## What reviewers say

**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.)

**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.)
