Nice watch to have for sure

Bought it 2 weeks ago use it more for walking with my job. Will always recommend Garmin watches to anyone that is looking for a good quality watch.

This watch has a lot of useful features.

This watch was a birthday present. I am still learning to understand and use the many features. I like the size of the watch face. It has a long battery life. .

Best running watch!

I’ve owned a few garmins, the forerunner 55 is my favorite. It was a great batter life and is a good running companion

Not ready, out of the box.

I wanted a running watch that displays distance run, pace, and time running. What I got was a watch that has a TIMER, as the main part of the display. I wanted to save my run, and there are several choices. It should vibrate when it completes the lap. Very weak. Last week I ran 14 miles. Mile 6 was 2 minutes for .2 mile. I don’t know what happened to the rest of that lap. Apple Watch was the backup and recorder 14 minutes for that mile. That has never happened before with a Garmin watch. I have to download the manual and see if I can get the watch to display the proper data. I shouldn’t need to do it. If I was running on a track I might use a timer but not for running on the road.

Love running with it!

I bought this because a lot of people that I run with have Garmin watch, so I thought that I would give them a try. So glad that I did! I have just ran the Turkey Trot, and it was so awesome to see all of my stats just by looking at my wrist. If you’re on the dance about getting one, just commit, you’ll never regret it!

Sleep Feature

Love the watch but recording sleep is confusing. Doesn't appear to do so accurately.

I bought this because it was cheaper than some of the other options but I have to say, it does not lack quality from the price. This watch is amazing. It tracks my runs and does exactly everything that I need it to do. I absolutely love this watch.

Disappointed in lack of activity profiles

I never leave bad reviews but maybe someone can learn from my mistake. I recently downgraded from a 935 to this 55 and I wish I hadn’t. Even though this is supposedly a running watch, it doesn’t have trail running or hiking activity profiles, which makes no sense to me. I also can’t find a stopwatch function. The alarm clock doesn’t vibrate as vigorously as my old 935 either which makes it less likely to actually get me out of bed in the morning. Definitely disappointed in this purchase. I own a lot of Garmin products (a bike computer, bike light/radar, power meter) and this is just so disappointing.
