This Tracker watch works accurately. I recommend this product highly.

Returned after 1 day. Buttons to small for ease of use.

Had fitbit for years and battery sucked this thing is amazing don't have to charge for over 11 days

Amazing watch. I use it to train for marathons.

So far so good..good watches..still a little bit early to know

Just out of critical care and needed an accurate heart monitor. This is just what I needed

Didn't track my sleep correctly so I'm returning it.

Great battery, easy to use, great for runs and workouts

It fits my needs and has excellent battery endurance.

Bought it around a month ago & so glad i did. Keeps me motivated.
