Mask Bros.

+305
Proof of Usefulness Score
Certified Problem Solver

Mask Bros is a legitimate, verified UK-based e-commerce operation (Mask Brothers Ltd) that gained significant traction during the COVID-19 pandemic, positioning itself as a cost-price supplier. External search confirms over 2,400 Trustpilot reviews and credible media coverage (The Grocer, Telegraph & Argus). However, the submission quality is poor, with hyperbolic claims ('everyone', 'most people') and confusing financial metrics ('marketcap: 17000000'). Technically, it is a standard retail operation with no proprietary tech ('Machinery' cited). The score reflects strong historical real-world utility and verifiable sales volume, tempered by a lack of innovation, post-peak market timing, and low-effort submission data.
