I have had the product for 7 months and I am satisfied.
I use it for music production (simple use).
It has not presented any problems so far.
I recommend it for those who want to spend their time entertainingly.
(Of course, it is not for professional use).
I use it with FL Studio and it does its job perfectly!
It is immediately recognized by the computer or console as soon as you connect the USB cable that comes with it.
The keys are the same as those of a laptop, soft to touch and with quick response.
The negative thing I find is that if you don't wear headphones, the keys' click will be a bit loud.
I still recommend it though, with such a price and brand, it is perfect even for beginners.

Comment update after 3 years of use: I didn't even realize that 3 years of countless use have passed, and it feels like I bought it today. FLAWLESS in EVERYTHING. It was worth every euro. I highly recommend it (but also with headphones due to the "click" I mentioned above).

Since the product is still available in stores, I decided to make a final update after 5 years of use. Everything I have written before still applies. (5 years is more than enough for its price) and it still works perfectly!!!
