Reviewed in Canada on June 26, 2025Verified PurchaseQue je suis content, facile d’utilisation et la durée de la charge est impressionnante comparativement à mon Garmin 520 plus qui se faisait vieux! Merci Garmin!!
- Reviewed in Canada on June 26, 2025Verified PurchaseI can build workout for my kicker without subscribing to zwift . Also the garmin ios app can push the workouts to the device!
- Reviewed in Canada on July 5, 2025Verified PurchaseMy boyfriend loves this a lot!
- Reviewed in Canada on February 17, 2025Verified PurchaseLots of data and features. Good size for viewing.
- Reviewed in Canada on October 7, 2024Verified PurchaseI was a bit concerned about buying the non-solar model, but this has plenty of battery life so we don't have to be charging it every day while on the trails. It has lots of features -- still learning them! Bought this to replace my eTrex 30 that had survived over 10 years of abuse. I enjoy the touchscreen option.
- Reviewed in Canada on September 3, 2024Verified PurchaseChanged from Edge 520 to Edge 530 in the past and never thought I would need the touch screen on 800 series. I am so glad I bought this one. New features available on it as compared to 530 are great to have .. and I really love the bigger screen size plus the touchscreen
- Reviewed in Canada on June 21, 2025Verified PurchaseReceived the product but it was clearly a returned item because the seal on the box was broken and the protective plastic on the screen was bubbled like it had been removed and then replaced by someone.

- Reviewed in Canada on July 15, 2024Verified Purchase1. Out of the box every feature is turned on, resulting in an almost unusable experience. You will be chirped at constantly with audio alerts and pop ups that make the core data you want (heart rate, power, speed, etc) mostly invisible.
2. The workout screen is awful. The text with your power target is so small it almost unreadable, certainly not useful when you’re putting a hard effort, and this awful screen cannot be modified to fix this. Also, you can only pause a workout step through the touch screen, and it is way too fiddly to do when you’re putting down power.
3. If you’re coming from another platform (I had a roam v1), Garmin won’t use any of your prior data (even after you link Strava and/or Training Peaks), so you’ll endure a week or two of constantly getting congratulated for new records, that are more n fact not new records.
4. The screen is higher resolution than wahoo but no more readable, thanks to garmin’s design, and perhaps just poor contrast.

5.0 out of 5 stars Excelente ciclocomputadora
Verified PurchaseLa calidad de Garmin se nota en este producto, tiene una curva de aprendizaje muy rápida, cambio su diseño respecto a la versión anterior el 830, este nuevo modelo es de pantalla táctil y aparte trae botones por lo que puedes usarlo de ambos modos; su navegación es muy rápida, ya vienen precárgadas las subidas de México, anteriormente tenías que cargar una ruta para que te marcara las subidas pero ahora detecta por donde vas y te muestra una gráfica de la subida, distancia e inclinación, trae también el sistema que te marca la fatiga, calculando tu pulso cardiaco mediante una Banda, estima cuánta energía tienes para realizar una ruta, es un aproximado interesante, además de que tiene muy buena conectividad, lo encuentras a mucho mejor precio aquí, solamente revisa periódicamente las ofertas
