The Garmin Forerunner 55 does an excellent job of what Garmin advertises.
After a week of use I am at 25% battery.
This is a combination of use in standby, with sleep tracking and 6 hours of GPS use (walking, cycling,..).
Brilliant battery!
I bought this watch largely because I didn't want a touchscreen.
Using the five buttons takes some getting used to, but works fine.
The screen is easy to read in direct sunlight, in the dark you can only read it when the backlight is on.
This can be operated via a button or with a twist of your wrist (you have to turn it on in the settings).
My scary point about the screen is that it is a bit small for the size of the watch case. But after a week of use you learn to live with it.
The sleep tracking works well and works together with the body battery.
These are very accurate. The scores correspond very well with how you feel.
The sports features are more than enough for the target audience for which this device is intended.
My scary real negatives are that the pedometer doesn't always register properly.
Sometimes he gives too many steps as a shake with your arm and if you keep your arm still while walking he sometimes misses some steps.
These are the pain points of most pedometers, but still a shame.
The last downside is: if I sweat very hard, my wrist is slightly irritated under the strap.
However, this is only with heavy efforts and not with normal use.
Looking back on my pluses and minuses, the Garmin Forerunner 55 is a very good device for its price.
There are more pluses than minuses so definitely recommended.
