## What reviewers say

Both whitelisted testers reviewed the Karoo 3. DC Rainmaker ran multi-month, side-by-side testing against the Garmin Edge 840 and Wahoo ROAM V2 (GPS/elevation data plots, battery-burn charts). Cycling Weekly did a hands-on but qualitative test on a Morocco ride, with no measured metrics. Both praise navigation and user-friendliness and call it a legitimate Garmin/Wahoo rival. Both note it is not meaningfully faster / slow to power up despite the new processor and RAM. On battery they diverge: Cycling Weekly found the 15+hr claim falls short in real use, while DC Rainmaker found the claimed ~30% improvement roughly holds (about 12-13hr realistic). No RTINGS or lab-benchmark source exists for this model. (Based on 2 reviews, 2 lab-tested, 2024-05-15.)

Praised: Class-leading mapping and navigation (best-in-class per CW; top-2 and a core strength per DCR); Superior high-resolution 3.2-inch display; Standout user-friendliness and setup; Solid GPS accuracy in accuracy testing.
Flagged: Not meaningfully faster / slow to power up despite the new processor and RAM; Battery life is the weak point vs Garmin/Wahoo (15+hr claim fell short in real use); Weak structured-workout player / interface needs improvement.
Disagreement: Display viewability splits them: Cycling Weekly calls the screen 'superior' and best-in-class, while DC Rainmaker, after 800km side-by-side against the Garmin Edge 840 and Wahoo ROAM V2, found the Karoo 3 'the least viewable of the three' in bright sun (though still usable — he 'never had an issue viewing the Karoo 3 screen'). They also weigh battery differently: DCR's ~12-13hr estimates roughly match the claimed 30% improvement, whereas Cycling Weekly found the 15+hr claim fell short in real use.
