Just today I bought a keyboard to replace my Sven Basic 304, which is almost a rarity. This keyboard, apparently, has several models and I got 1576 - instead of the right Windows key, a functional one is installed, therefore, I get 4 more buttons (F5 - F8) that work under Windows 10. The keys are not programmable (but I don’t need it), it doesn’t have any drivers and doesn’t require it. Installed out of the box and everything works. I really wanted to adjust the volume on the keyboard - here it is and it works + mute and pause. 1. Buttons are pressed easily and quietly. Yes, indeed, the larger the button, the more noise it makes, but in general there is no fierce rattling and in general the keyboard is noticeably quieter than its predecessor. 2. Enter renamed to "Input" and made into one line (usually two). Unusually, although I don’t seem to miss with my little finger yet. 3. The top buttons, including PrtScrn and Pause, are made separately and smaller than the rest. This is very unusual and still causes discomfort - Punto Switcher is tied to Pause, but I use PrtScrn daily, because. I work with graphics. I hope I get used to it. I write almost blindly, because the buttons for me, even bright, even faded, did not bother. Everything is very even, neat, I really liked it, although I did not plan to buy it when I went to the store. Overall, I'm happy with my purchase and hope it lasts a long time.
