1 review for Garmin Forerunner 645

  1. Damon Coleman

    The smartwatch itself – a revelation. On the other hand, access to the smartphone application that supports it (not too bad by the way) is shameful – seemingly available through google play, but in practice it does not work. You have to smuggle the huawei ecosystem on your smartphone, confusion is terrible with this.

    Also a small minus for the incompatibility with Endomondo
    A modern watch, visually nice, very functional, perfectly performing all its functions, perfect for both practicing some sport and analyzing the state of their health. Plus a long battery life!

    I really recommend it to anyone who plays sports for now, the battery at maximum settings, GPS pulse testing every now and then, etc. The best thing is that it has a microphone and a loudspeaker in case of W you can answer an incoming call. The battery lasted 10 days
