JannekeR 4 Small smart watch!It is the smallest on the market and is very elegant. I’m happy with the size.I bought it to monitor my heart rate and it does so accurately.I did have problems with the body battery and stress level meter. However the Garmin support team explained that this is because of my naturally high heart rate, not the watch itself. So if you have a fluttery heart like mine and want a watch that tells you stress levels, this may not be the watch for you. However, if you want to measure step goals, exercise or heart rate, go for it!Despite other reviews, my battery has lasted a week or more at a time.Happy with my purchase!
