Battery will not last the day, let alone to use to track sleep in a 24 hour period. I’m a long time Apple product user and this one I returned. Battery life is equally important as the brand.

This is a really cool watch. I love all the features of it. But the battery is comparable to the one of the SE iPhone.. I have to charge it at half day. I love it other than that though.

If you don't want to miss any notifications from your cell phone but also want to monitor your physical activity and sleep, don't wait any longer and get this smart watch right now, plus it looks great on my arm.

So far so good - love the watch. Been wearing it for about 2-3 weeks. Battery did seem short one day, but I had used it a lot on that day, so could be normal. Otherwise, fantastic.

Right now, I love this watch, I love how it tells you how many steps you take how many calories you burn in your heart rate plus it's very convenient for incoming calls when I don't have my phone by me

Its perfect for my needs, has been a great help when i lose my phone under the covers, and the color is pretty. Also makes it easier for me to stay in contact for emergency or calls that need to be answered.

My boyfriend loves it!! Purchased for Valentine’s Day and it’s exactly what he was looking for in the gym, monitoring his heart rate, and just overall upgrading his wearable tech!

[This review was collected as part of a promotion.] I rate this product because this way is it helps me seee time answer phone calls and records how many steps I took

I bought this mainly as a step counter, but was amazed that it came with hundreds of other features and at such a great price. I can’t wait to get into all kinds of fitness shenanigans my new Apple Watch.

[This review was collected as part of a promotion.] High quality watch, just like other Apple products I own. Much better than my Fitbit in every way, easy to set up once it has been synced to iPhone, and very customizable for my needs.
