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.

Garmin is turning its attentions back to the fitness tracker with the Garmin Vivosmart 3, with wellness at its heart. It's slightly less focussed on sport than the GPS-toting Garmin Vivosport , with stress tracking, guided breathing exercises and sleep monitoring joining exercise detection, rep...

Lots of features on offer; including VO2 Max; Supports some strength activities; Good price

No GPS; Display can be unresponsive sometimes; Heart rate not the best at high intensity

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.

Exactly what I wanted, talks to my photo software and allows me to measure all the things my photo can't. Comfortable fit and easy to use

Easy to use and what i want in a watch

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.

The thinner-and-lighter trend isn't just dominating smartphones and laptops-fitness tech companies are constantly trying to make "the next big thing" as thin and light as they possibly can.

Easy-to-wear design; Good new rep-counting feature; Auto-recording feature and on-device activity menu; New estimated VO2 max and fitness age scores

Cannot change out bands; Heart rate monitor is inconsistent at high BPMs; Sleep tracking isn't as comprehensive as that of the Alta HR; Limited on-band music controls; Garmin Connect badly needs an overhaul

The Garmin vivosmart 3 is essentially a sleeker vivosmart HR with support for strength training. Unfortunately, this new strength training feature mostly disappoints us. In theory, the VS3 is supposed to quantify your reps, sets, and rest times as well as automatically recognize exercises.

Comfortable and water resistant; Thin; sleek design; Built-in wrist heart rate monitor; Smartphone notifications + control for music and VIRB action camera; Moderate price point

Strength training feature is disappointing; Does not connect with external HRM; Display is average at best

New fitbands seem to be a dime a dozen but if a brand wants to set themselves apart from the pack they need to come with something different. With the Vivosmart 3, Garmin are attempting to do just that. Any old device can measure steps these days but how many can count reps for you

It's interesting seeing Garmin take the Vivosmart series in a slightly different direction. By shrinking the display down and making it on-demand only, it's going to appeal to a slightly different market than that of the Vivosmart HR (or even HR+).
