According to the product specialist

Pros
Charge the battery easily via the derailleur itself!
This derailleur features MTB technologies for a robust build.
The derailleur ensures consistent gear shifting performance, even under load on a steep climb or a technical descent.
The perfect product to optimise your drivetrain!
With ceramic bearings that last a long time and run smoothly.
Not just functional but also with a stylish look.
With this derailleur, you can easily convert your 2x12 GRX groupset to a 1x12!
MTB inspired technologies make this derailleur very robust.
Thanks to the Automatic Impact Recovery function, the derailleur moves along with the bike's movements and returns to its original position immediately after an impact.
The battery is well concealed inside the derailleur, where it is protected from the elements and any external impacts.
An oversized derailleur cage is the perfect product to optimise your drivetrain!
This derailleur cage features durable and efficient ceramic bearings.
The cage is not just functional but also has a stylish look.
Cons
The derailleur is only compatible with an 11-34 or 11-36 cassette.
The derailleur can only be charged with a brand-specific cable.
Only compatible with Di2 derailleurs.
Mounting the cage is a meticulous job that requires time and concentration.
The required battery is not included.
