I've had this for about 2 weeks. At first the battery life was fine, not anywhere near the advertised 5 days but it was ok. I went into the settings and shut everything that drains the battery off, dimmed the screen, shut off phone notifications, shut off auto track feature and heart rate monitor.

A very easy to use device with plenty of information both from the tracker itself or the app. It detects your activity automatically without presetting. I returned my Samsung Gear Fit2 Pro. This one is a lot better than the Gear.

Bought this for my teen daughter. She absolutely loves it! The fact that it's waterproof was why we got this one. I love it because it helps her stay active.

You can find this a whole lot cheaper elseswhere!

Acted beyond expectation. Hardly notice that it is sitting there and doing its job. The Garmin app is good and has given me some news about me, a little fun. If you sync to their site too, there are more ways to visualize data. But, I used it around the clock.

I purchased my own from another site and loved it and so I decided to purchase one for my husband. It is very durable, accurate and very comfortable to wear. The only thing I am a little disappointed about is the battery life. Several reviewers state its average battery life span is 5 days.

Garmin is pushing its activity tracking to a new level with the Vivosmart 3. This wrist-placed wearable is Garmin's third generation of the Vivosmart, after skipping the number 2 in favor of the Vivosmart HR+ .

I bought this watch a week ago as part of my get fit initiative and it's great. It has some really good features like sleep analysis, stress management as well as step counter and heart rate measurement. The fact it's waterproof is also a real bonus as means I can wear it in the pool.

Bought for my wife and she lo as it. It fits her wrist well and it is quite accurate. The size is just big enough to make the screen usable for texts and to see valuable information

Works well. We use it for tracking heart rate and sleep, not for 'standard' activity-type tracking. Effectively we are using it for medical monitoring, although the instructions have lots of legal jargon saying you can't do that. The battery lasts a number of days between charges, which is good.
