Approximately 1.5 years of experience. That's the whole life of the keyboard. It starts to make noise from the first week (and all the buttons are the same, that is, it is not silent, it's all marketing). A bad product creates the illusion of quality, but in fact it is expensive, poor quality, loud, short-lived. Unfortunately, there are practically no analogues in the price range, but even here there is no quality for such an amount. The review also applies to this model in a differentcomlor (although I don’t see the difference)
I wanted to add some visual interest to my review, so I've included some photos.
