1 review for Garmin Forerunner 45S

  1. Gavin Dunn

    In general, if you are 4, I do not recommend changing. It is convenient to add side gestures – it makes it easier to access some functions. It’s cool to manually turn on and off alarms from your wristband. Bigger characters are nice – Polish letters, however, are some miniature (tails). Besides, I do not see any more advantages.

    A smaller battery. In my opinion, the clasp fits worse than in the 4th. The PAI function is a complete misunderstanding. I will eat your battery for breakfast. This option starts measuring your heart rate every 1 minute. You know what happens then. Overall, it’s not a revolution. Not a step forward, not a step back. I would say a step aside. They improved something, made something worse. The band had a chance to sweep the market, but they probably got along with the competition not to do it and that everyone would get a piece of the cake.
