## What reviewers say

**Sigma ROX 12.1 Evo** — Only one whitelisted tester (BikeRadar) published a hands-on review of this exact model. BikeRadar rated it 2/5, praising easy route-following and rich training data but panning meagre battery life (10h with a heart rate monitor only; 4.5h navigating with sensors), a rain-triggered touchscreen, cheap build and an uncompetitive £379.95 price.
