This is one of the best in class, especially the battery life and solar power. Each time I ride it outdoors, it charges back 30% and hardly loses 6% in three hours of riding. The tracking is very, very accurate, and the auto pause works nicely. I sometimes find a sync delay of a few seconds, but that's manageable. The brightness is pretty good, even in a bright day.

Works perfectly and unbelievable battery life. I used it for a 7 day tour from Mumbai to Goa and had to charge only once (that too as a precaution as it was nowhere close to being discharged). The solar function seems to be of limited use though. I am a normal user who records the days activity with a heart rate and cadence sensor. Worked perfectly!!

Accuracy is top notch and works without any lags even on congested areas. Battery life obviously the best in the market and with solar-panel, it's even more better. Value for money!

Excellent device with amazing battery life! I think one can do 1000kms without recharging the battery if driven in day light and dark conditions combine too as solar recharge does work
