20 days after the purchase, I began to pay attention that the D button shines somehow differently, I began to look closely and saw that the paint was falling off or something. In fact, I played the keyboard for a couple of hours in the evening after work. Do you think Razer is the norm? I came to Amazon where I bought it, they say it's maintenance, not a guarantee. But they say go to the warranty department. In the warranty department they say we will send it for examination. This is at least 20 days. Thank you Razer!
