Coospo S10 Power Meter Review // Another Gamble at JUST $88?

The video reviews the Couspo S10 power meter, a sub‑$100 device that promises the same specifications as the Think Rider PP5 but at a dramatically lower price point. The reviewer sets out to determine whether the S10 can deliver the advertised ±1% accuracy and consistent performance expected of a serious power meter. Testing revealed several critical flaws: residual torque after hard efforts caused the meter to retain a non‑zero baseline, inflating power readings until manually re‑zeroed. Firmware version 1.72 reset the battery indicator to 0%, a bug shared with the Think Rider, and the unit exhibited a noticeable lag of about one second. Across multiple indoor and outdoor rides, the S10 consistently ran 5‑6% high, far exceeding its claimed tolerance, and required frequent recalibration. The reviewer highlighted specific data points – a 178 W reading versus a 175 W baseline, a 1300 W sprint that caused the meter to “crap itself,” and repeated instances where the device drifted by 10‑15 W after short sprints. He likened the need to constantly re‑zero the meter to “brushing your hair in a hurricane,” underscoring its unreliability in real‑time use. These findings suggest that ultra‑cheap, white‑label power meters like the Couspo S10 can mislead cyclists seeking accurate training data. If larger manufacturers adopt similar hardware, the market could see a broader erosion of trust, echoing past controversies such as the Shimano power‑meter debacle. Consumers must demand transparent performance claims, especially when price points appear too good to be true.
