## What reviewers say

**Doro C300** — Two whitelisted testers (Tom's Guide, TechRadar) reviewed the exact Doro C300 after weeks of hands-on use; both recommend it as a comfortable, high-looking all-mesh chair at a mid-range price. Both flag armrests that slide out of place too easily. RTINGS, Wirecutter and PCMag published nothing on this exact model; the Pro/Pro V2/S300 variants (TechRadar has a separate Pro V2 review) were excluded. (2 sourced reviews.)
