Case Study: Mazuma Mobile achieves market-leading customer trust and top review rankings with Trustpilot

How Mazuma Mobile hit the top spot with reviews

Mazuma Mobile, founded in 2006, is a UK market leader in mobile phone recycling (about 35% market share and ~150,000 phones recycled per month). Because customers must trust the company enough to post used phones worth hundreds of pounds, credibility is essential; although Mazuma had many unsolicited testimonials, online third‑party review sites were often negative and offered no way to respond, making it hard to measure and showcase its service excellence.

In April 2010 Mazuma adopted Trustpilot to collect independent reviews and publicly reply to feedback. Over four-plus years it amassed tens of thousands of mostly five‑star reviews and reached a TrustScore of 9.8 (May 2014); the visible customer stories and seller ratings also boosted Google Ads performance and click-through rates, strengthening credibility against major competitors.
