aiwako IP68 Waterproof Fitness Tracker Activity Bracelet with Heart Rate Monitor, Pedometer, Calorie, Blood Pressure, Blood Oxygen, Bluetooth 4.0 Smart Band for Android/IOS, iPhone 8, iPhone X - Blue

Arrived within 2 days of ordering. Easy to set up and comfortable to wear. Still getting used to all functions. Although waterproof it didn't work well for swimming measurements. It kept resetting. Button/touch point very sensitive and seems to be affected in the water. Also keeps vibrating at night.
