Want to stay fit and use technology to help you instead of just going out and doing some running with just your tracksuit on? Band 2 Pro is a device for you. Huawei’s activity tracker is currently on sale on Amazon, with its price slashed from $69.99 to mere $49.99. For such a relatively low price, Band 2 Pro offers a plethora of useful (or moot, if you are an old-timer) features, such as 5ATM waterproofness, high-quality GPS tracking, heart rate monitor, sleeping, walking, running and swimming modes and more.
