Trabold Side Channel Filters: Specs & Performance

hi,
Does anyone have experience with Trabold filters?
I mean, if you install it and change the oil normally, it definitely can't be worse than it was before.
But what about the extended oil change intervals?
It is said that the oil can last for 100,000 kilometers without needing to be changed.
The standard filter should normally be replaced every 15,000 km.
Has anyone installed a differential filter like this before?
greetings

Hi!
I don't entirely trust the system, but here: http://www.2literauto.de/Subjektiv/Verschleiss/verschleiss.html
Has anyone installed this in their 3L Lupo and documented the process?

Best regards,
