Review on Keyboard A4Tech KV-300H gray by Mateusz Kot ᠌

Got pros: I liked the design and the layout is normal (in contrast to the idiotic Logitech with a shortened left shift). Since it is wired, it is insensitive to radio interference and works until the OS is loaded. With wireless tormented. Its cons: The keys rattle with a metallic sound, I was counting on a quiet operation, compared to the previous Microsoft Designer, an order of magnitude worse. Still push hard. Doesn't work in keyboard ports (USB-1)
