Tracks steps, mileage, sleep, heart rate, pulse ox and more. Can link most apps and phones so that your notifications come right to your wrist. Helpful for home monitoring and not missing a text when you're stuck in a meeting. Afraid to sleep in

This new tracker has the common features (sleep stages, heart rate, stress) and the new Body battery that is very interesting and also pulse ox. I already own the Fenix 5 & Vivosport, I highly recommend it!

Coming from a Fitbit Alta HR, the Garmin vivosmart 4 feels better and lighter on my wrist. I like the Garmin Connect app better than the Fitbit app. Its not perfect but Im enjoying it more than the Fitbit. Battery life has been good.

I bought this watch a month ago, it has some really good features rest sleep and fitness I absolutely love this watch it's so easy to use, very easy to pair up to your phone.

I bought this a month ago and love it! it does everything i need. Was primarily purchased for swimming as previously had the fitbit 2 however the fitbit doesnt have the time or heart rate.

Only used it for couple days then have to wait for birthday to come. Halford's asked for review for chance to win ￡100. Seems good. I like the feature of stress level I think I'm actually more stressed than I released and also have lower oxygen levels in my blood than the normal healthy range hoping...

Garmin's vivosmart 3 fitness tracker tried some interesting things, but it didn't follow through so well on all of them. This year, the company not only needed to make up for the vivosmart 3's faults, but also create something to go head to head with the upcoming Fitbit Charge 3 .

Thin; lightweight design OLED display is much better than the vivosmart 3's Accurate fitness tracker overall Advanced sleep metrics are very useful Body Battery is useful for determining how tired/energetic you are Pulse ox sensor is nice to have on a lower-end tracker 5ATM water resistance Garmin...

No phone-to-GPS tethering option Narrow display can be difficult to use Pulse ox sensor is sometimes off; doesn't take readings all night

For the same price, the Fitbit Alta HR has a similar look, feel, and functionality, but with more flexible fashion options thanks to its swappable bands. It also has a more responsive touch screen and a better user interface, but less detailed metrics.

Accurate; Long battery life; Automatic activity tracking; Measures blood oxygen levels, sleep, stress, and body recovery; Slim, sleek design

Touch screen could be more responsive; Uses proprietary charger

Awesome to see sleep cycles, calories burned, get messages from phone ( texts, weather alerts and even new music available on my Apple Music.) Crutchield excellent service as always..quick delivery and and new condition. Will always buy from crutchfield if available.

Waterproof; good battery life; Garmin connect app is great

Non interchangeable bands

extremely pleased with my Garmin Watch; does all I need to track both my exercise and health requirements without being too obtrusive. Fits flat onto my wrist, so very comfy to wear both in the day and at night, when it tracks my sleep patterns.
