I received this specific product as a gift in January. It is now June and two devices have already broken, but they have been replaced due to the warranty. With daily use, yes, it boils the eggs in the specified time and the sound notification works properly, but at some point, it decides on its own not to work again. And both times, it's the exact same problem. I would not recommend it.

I bought the kettle on 31/01 and with minimal use, it broke and the boiling does not start.
Wasted money!!!

Due to previous experience with a device of this kind, I can say that it is a premium device.
But... I have reservations about the company (brand).
It fits 8 medium-sized eggs comfortably and has a timer and audible notification.
We will see about its durability.
