I'm wondering about the Kuku Maker: can it really prepare an authentic espresso?

Espresso extraction with the Kuku Maker and a Timemore S3​

This coffee machine uses centrifugal force extraction technology, which raises questions. The extraction pressure is not known, as it relies solely on centrifugal rotation speed to make the coffee.

Similarly, as with the Kuku Maker, the coffee "falls" at the end of the process. We therefore don't have the possibility to visualize the extraction as with a bottomless portafilter, and evaluating the quality of the flowing coffee becomes difficult. Normally, it is for example possible to visualize the presence (or absence) of channeling4 tips to avoid channeling with a bottomless portafilterDiscover how to avoid channeling during your espresso extractions with a bottomless portafilter. during extraction.

Does the Kuku Maker offer a unique brewing method approaching espresso, but without ever perfectly matching it?
What do you think?

This machine remains captivating, and it seems promising to me to continue following the evolution of this project. Nevertheless, I didn't participate in it because my interest in this project lies solely in technological curiosity. I think I would miss the absence of certain steps in preparing my espresso, such as using a WDT or tamping.
