originally intended to use K810. It was my responsibility to switch from Apple's little wireless to a comparable one. On a PC, Eplovskaya won't function properly without a bootcamp. However, Eplovskaya has unreasonably cool "mechanics" (whether or not there is a membrane is immaterial; for me, it serves as a point of reference), therefore something comparable in terms of performance was required. Furthermore, the k380 is not inferior to it in any way when it comes to "mechanics". If you install firewood on the K380, Capslock, it will light up when you push it directly on the screen, allowing you to continue living:) It appears to be entirely composed of plastic, yet it is constructed in such a way that, even after seeing the lovely Apple model, I have no doubts about how well it was done. K810 did not take for two crucial factors in my opinion: 1. The built-in battery has a significantly shorter lifespan and requires more frequent charging, although I'm used to not giving it any thought on the Apple model. 2. Although I frequently use them, the k810 lacks rewind buttons. Because of the k380's adjustable buttons, I was able to get exceptional functionality. I can now refresh the website with one button (useful on the laptop by default! ), cancel the currently open window with another, and enter search criteria with the other two (WIN + Q). But because there are so many options, everyone can find what they need.
