What customers say about "Key Specs"
TomTom Runner GPS Watch +Heart Rate Monitor
  • The display is easy to read, and the light can be set to stay on during the run.
  • Size - It is reasonably comfortable and not too bulky.
  • The main display is easy to read and you can scroll up/down to get other information while you run.
  • GPS signal - When it is cloudy, getting a GPS lock can take some time.
  • The two smaller displays at the top are a bit small.
Garmin Forerunner 15 GPS Running Watch
  • The watch is easy to use (I did not have to help her learn to use it at all), and she says that the display is easy to read with all of the info she needs in a quick glance.
  • The display is easy to read and the buttons are easy to push.
  • It has a large display for time and distance that makes it easy to catch a quick glance.
  • Nice product, with on-line site to display map of running route, complete with elevation and pace.
  • If you are looking for a budget gps running watch then look no further. The reason I did not give it a full five-star rating is for two minor reasons.

What customers say about "Functionality"
TomTom Runner GPS Watch +Heart Rate Monitor
  • The controls are simple, responsive, and easy to access.
  • Everything is controlled with 4 switches integrated around the GPS sensor so that there is no need to fumble with finicky touch screens or a plethora of buttons while trying to run.
  • Love my new watch and how it tracks my running speed and distance and heart rate.
  • Love also all the functions it provides, like being able to race against previous runs.
  • Does what's is expected of it - keeping track of your pace rste, distance, time, heart. So far happy with it.
Garmin Forerunner 15 GPS Running Watch
  • Main screen with display time and then across the bottom you can scroll through: Date/ month, steps, goal, miles, and calories
  • This is a functional runners watch that ticks most of the boxes.
  • Overall, it functions accurately and is a band-aid solution to my need for a watch with a longer battery life.
  • Great simple GPS watch for those who don't want/need a multi-function fitness tracker/smart watch. I had a FR10 for many years and loved it.

What customers say about "Features"
TomTom Runner GPS Watch +Heart Rate Monitor
  • Waterproof - It rains a lot where I live, and having a watch that is actually waterproof rather than just water resistant is super important to me. I wish that I could handle bad weather as well as this watch!
  • I can sych data with my iPhone via Bluetooth. Easy to use.
  • TomTom is continually updating the software, and seems responsive to customer input.
  • Great battery life and very intuitive once you get used to the buttons in the strap and not on the sides of the watch.
  • This watch has a surprisingly short battery life.
Garmin Forerunner 15 GPS Running Watch
  • Water resistant up to 50 m ( took my kids to Soak city all day and showered in it- no problem)
  • It's stood up to accidentally being dropped in a sink filled with water.
  • On the plus side, it did survive one obstacle race with a fair amount of mud and water submersion.
  • Longer battery time-8 hours training on garmin 15 versus the 5 hours on the Garmin 10, but will go around 8 weeks in fitness tracker mode.
  • Battery is rechargable but you have connect the cradle which is not always feasible.
