Wattmeter 4iiii Shimano R8000 Precision 3D Ultegra

I am selling a 4iiii Precision 3D wattmeter on a Shimano Ultegra R8000 left crank with a length of 172.5 mm.
The Wattmeter was bought from MTBiker in February 2023, so it is basically only a little over half a year old and is of course under warranty. It is in perfect condition (it was hardly used).
The reason for the sale is the transition to a new bike, where unfortunately it will not fit due to the rear construction of the frame.
