I bought this to use for managing chronic illnesses. I read a lot from other people about the Body Battery function. Overall I do like it. I'm not usually the type to use a lot of new tech or even wear a watch. I will say, it does work pretty well. There are loads of features you can use for daily activity, but I'm not at that place right now. It basically just calculates your pulse rate and oxygen levels, then uses that to determine your sleep score, body battery, and stress levels. I'm not sure what else I expected. My condition causes high heart rate and my watch pretty much tells me I have danger levels of fatigue most of the time. I thought it would adjust to my baseline and tell me what is high and low "for me", but it seems to be heavily centered around the average recommended sleep time and heart rate for adults. There are tons of functions in this watch and I really don't need 90% of them. You can upload calendars, menstrual data, music, and alarms. Stopwatch, timer, all that. The watch band is easy to clean, though, and it's super light. Battery lasts at least six days. It comes like 80% charged. The battery charges 100% in less than an hour. It definitely is a quality product. Again, I'm just a bit salty about it not adjusting to my personal baseline. I'm still hoping it will eventually, but it's been a few months so I don't think it will.

too much work to set this watch, not to mention, you need múltiples apps to work with it.

The best fitness/sports watch has so many features to it complete health watch. Worth the buy.

I bought this watch for my son and he likes it!

absolutely love the watch

Great running watch for my Teen! Easy to use with a bright display. It also saves your workout so you can go back and look at the stats/compare.

Bought this for our daughter who runs cross country and it’s perfect. The battery life lasts and she says it is easy to use. It’s perfect for what we got it for

This has been great for helping me track my running and train for my upcoming race.

Love my Garmin! So many cool features!

It was exactly what I expected after reading on-line reviews
