According to the product specialist

Pros
A double-sided power meter allows you to measure the power transmission of both legs individually.
Thanks to the Automatic Terrain Selector, you are assured of accurate power measurement on different types of terrain.
With an IPX7 waterproof rating and a battery life of up to 550 hours, you are guaranteed endless fun.
Very accurate force determination with a deviation of up to 1%.
Suitable for Shimano 12-speed cranksets.
At 123.5 grams per pedal, the Assioma Pro RS power meter is the lightest in its class.
Thanks to the IAV power system, the power meter provides highly accurate data no matter if you are using round or oval chainrings.
The internal battery will last for more than 60 hours and is easily rechargeable via USB.
Thanks to ANT+ and Bluetooth connectivity, the power meter will easily pair with your bike computer, favourite training programme or the Favero app.
The Assioma Pro RS provides insight not only into your power output but also other data such as cadences, Power Phase, PCO and Torque Effectiveness.
Cons
The CR2032 battery is not rechargeable, so you may need to replace it from time to time.
This power meter is only compatible with road bikes and is not compatible with SPD or other MTB cleats.
