According to the product specialist

Pros
Bluetooth Smart and ANT+ technology makes connecting with other electronics a quick and easy task.
2 separate power meters, which can be used combined or independently.
Precise measurement of the applied power (only +-1,5% deviation)
Bluetooth Smart and ANT+ signal for communication with your cycling computer.
Easy Zero reset by just pressing one button.
Wireless system updates possible.
This powermeter has proved itself high on the reliability scale.
Thanks to the crank arms, spider and optional chainrings one can easily adapt/ switch out the powermeter.
The double-sided measurement gives an exact representation of the generated power.
This power meter transmits a Bluetooth and ANT+ signal, making it compatible with almost all bike computers.
Cons
The CR2032 batteries cannot be recharged, so they have to replaced every now and then.
Only suitable for Dura Ace chainwheels.
You may need to replace your bottom bracket with one with a DUB fit.
