Delvfire Ember Fitness Tracker with Heart Rate Monitor | Waterproof Slim Smart Watch with Sleep Tracker, Step Counter, Calorie Counter | Apple iPhone, iPad, Android Smartphone Men, Women, Kids (Black)

This devices is a great product. Its sits very comfortably on my wrist and half the time i forget it's there because of its small and slim design. It keeps track of your steps accurately and you can connect it to your phone via Bluetooth and use the app to look at your step count, heat rate and sleep.Ive never used the sleep tracker as i don't like to sleep with object around my wrist but im sure it works great like everything else does on this product.

I bought this for my son. Its fab! And such a great price. Great for a little wrist too. Totally recommend this.

Arrived quickly but not something that was easy to get up and running

Because it’s made from rubber it can be difficult putting on clothes with sleeves

The battery needs charging every 3rd day. And the straps have to be removed to do this, it is a real struggle to do this.you get what you pay for

Good product. For a seven year old this did everything they wanted. Better value than the Fitbit

Strap broke within the first month of having it.
