SHANREN MILES GPS Bike Computer - BLE & ANT+ Wireless Cycling Computer with Power Estimation, Automatic Backlight, IPX7 Waterproof, Synchronized with Bike Taillight - New Upgraded GPS Bike Speedometer

My old bike computer, that was built into my headlight, was just so unaccurate over time. Where I found this one, really good specs, and rated high on GPS and had to give it a try. I was not dissappointed, this one worked out great. For one thing, it is so easy to install, a whole 30 seconds, it was already charged. And out of the box, mounted, connected to GPS and all the display options kicked in, and was really impressive. It connects perfectly to my android app, and give a really granular level of details that was practically jaw dropping. Really nice to twist and pop in the pocket when running around the shops with that quick release mount. No cons, really worked out great for me, where I am very happy with the purchase.

Unit uses GPS for speed and distance data. Unit shows GPS working with strong signal, but no speed or distance data is displayed. All zeros. There is no support for this unit on company website, and no email or telephone for support. Finally, unit does not connect with their own Android app, even though Bluetooth on my Android phone sees the unit. Returning to Amazon, and I won't be buying more unsupported products from Shanren. The one positive note, unit connected easily with third party cadence sensor and heart rate monitor.

08/17/2021, Got a new item + a speed sensor. Everything works perfectly so far. Nice device, it does everything you need!Get a screen protector, screen scratches easily.09/01/2021 The devise was impossible to pair with my phone on the second day of use ... item returned.For MTB riders, a speed sensor is mandatory to get accurate data without it, this devise is useless in North Carolina trails.

So far I like everything about it, if I were more adventurous it would be nice to have a color screen with turn by turn directions and upload able maps. But for the money it's worth it.

Muy complicada de configurar, si se quiere conectar con Strava se queda preguntando si autoriza y no sale de ahí, no reconoce todos los sensores
