Pros of the Garmin Forerunner 45S:

  • Smaller and more compact. What makes this model stand out to most users is the small size of the watch. The Forerunner 45S is only 39mm, which means that this model is the essential model for users with smaller wrists in the Forerunner series. The Forerunner 45S fits snug and comfortable around the wrist, with a silicone base to decrease wrist burn during workouts.
  • Routable maps. With the Forerunner 45S, you can now customize maps and routes with GLONASS and Galileo GPS protocols which allow it to track in a wider range of environments and terrain than what can be achieved with traditional GPS technology. The mapping technology is now colored and interactive, which allows you to receive even more detailed and visually attractive routes based on your location.
  • Pulse oximetry data. Like most models in the Garmin Forerunner series, the Forerunner 45S also analyzes heart rate, heart performance conditioning, and heart rate with oximetry data to provide variability based on a wide range of different performance types to give real-time assessments of how you are faring during your workout and how long you can continue before you reach various thresholds.
  • Comes with preloaded activity profiles. The Forerunner 45S  is designed to appeal to a wide range of fitness activities.

Cons of the Garmin Forerunner 45S:

  • Subpar battery life when compared to other models. Unfortunately, the Forerunner 45S just doesn’t do well with battery life capabilities, especially compared to other models in the series. This can be expected though due to the increased amount of superior features that have been added to Forerunner 45S.
  • Doesn’t work well with other apps. One of the convenient abilities that come with some smartwatches is the ability to customize the watch with other apps that track running or jogging in ways that you enjoy. With the Forerunner 45S, you have to use its features exclusively.

The Downsides

As a running enthusiast, I found it frustrating that there were limited review sites available willing to give me an honest opinion on the latest technology to aid my hobby. I am certainly not trendy (my kids will testify to that), however I am an early adopter and just love getting my hands on the most up-to-date gadgets.
