Firstly, I did not like the packaging. It was delivered in an old box. It already had an Amazon tag(invoice) sticked and removed, so I could partially see it. It seemed like someone had returned the product and the same was delivered to me. So I thought, maybe the insides will be good. I plugged it in and started pressing keys and if I pressed the keys a little harder, unpleasant crackling noises were coming. This is not why I ordered the keyboard. So I returned the product. I am very unhappy with my experience.
