According to the product specialist

Pros
Can be used as an ANT+ bridge to Apple TV and other Apple devices.
Highly accurate heart rate data due to its optimised heart rate measurement system.
Data can be collected easily from ANT+ sensors and exchanged with your smartphone via Bluetooth.
Your Viiiiva can store up to 65 hours of training data.
Lasts for up to 200 hours on a single CR2032 coin cell battery.
With a battery life of 400 hours, a battery will last for about a year if you train one hour a day.
Can connect with your sports watch, bike computer or fitness equipment via Bluetooth, ANT+ or 5kHz.
Can connect with a Bluetooth and ANT+ device at the same time; this is ideal when you exercise with multiple devices, like a bike computer and a sports watch.
One of the lightest heart rate monitors, allowing you to display your real-time heartbeat on your favourite exercise machines.
Consists of conductive rubber, which is highly sensitive and capable of accurately detecting your heart rate in all conditions.
The patented honeycomb pattern minimises the chance of the Hammerhead heart rate strap moving around.
Easily connect this heart rate monitor with multiple devices via ANT+ and Dual Bluetooth.
Measures R-R variability, providing you with information about your heart rate variability while you're exercising!
ANT+ and Bluetooth connectivity allows you to connect the Polar H10 with almost any bike computer and smartphone.
Accurate measurements and fast heart rate display.
Has an internal memory for one training session, so you won't have to bring your bike computer or smartphone.
The Polar H10 can even be used in water.
Can connect with two Bluetooth devices at the same time.
Cons
This product uses a replaceable coin cell battery, so it's not rechargeable.
The Polar H9 has no memory function or accelerometer. For these features please consider the Polar H10 heart rate sensor.
Equipped a replaceable CR2032 battery, so it can't be recharged via USB.
