Given that I work at a PC, and also spend my free time at a PC, the low-profile Logitech MX keyboard was a blessing. Unfortunately, it wasn't great for gaming, but even so, it withstood some pretty rough treatment for 3 years. Once you get used to low-profile keyboards, you don't want to go back to the high-profile ones. You can always raise a low-profile keyboard, but lowering one is much harder, if not impossible. The Corsair K100 AIR Wireless keyboard was my dream one. A low-profile mechanical gaming keyboard, with the exact key layout I wanted (gaps between the F1-F12 keys, no extra buttons on the sides). Unfortunately, after just a month of use, I realised that the durability of the keys wouldn't last long. The keys no longer felt as smooth and were creaking. From numerous reviews, I understood that I would destroy the keyboard in no time. So, at least for gaming, I started looking at another keyboard and ended up buying the Logitech G915 X LIGHTSPEED. I tried it for about 2 days and even though it didn't suit me, I concluded that I couldn't buy anything better at that moment and unfortunately, I kept it. The keyboard itself isn't bad, it's nice, good quality, not too high. But the tactile buttons are only good for gaming, and not even always then. I've never had so many misclicks on any other keyboard. I curse the keys on the left side, and the longer I use the keyboard, the more I hate them. On top of that, the charging behaves crazily; when I unplug the keyboard or just turn it off and on, it immediately has 10 to 20% less battery and starts charging straight away. It's been doing this since I bought it, I even tried exchanging it and the second unit did the same thing. So if you want to use the keyboard wired to save the battery, you'll actually put it under even more strain.
When I couldn't take it anymore and got a Keychron K5 Max Swappable Gateron RGB Backlight Brown Switch, I soon found out that you can be happy for half the price. When you switch to wired use with the button, the battery isn't used at all. The setup via a web browser is great, and compared to those crazy applications from Logitech and Corsair that clog up your computer, I had everything set up in 15 minutes. The Brown switches are great even for typing, although I wouldn't mind if the press was a bit more definite. I definitely don't recommend Red switches for typing. The backlighting isn't as pronounced and nice as on the Logitech, but I don't have the keyboard for show, but to earn a living on it and for it to be comfortable to work with. And the fact that the Czech characters aren't as well lit, well, when you need to see them you can, and the other keyboards didn't even have them, so for me it's just a plus. Most gaming keyboards are US layout only. The Num Lock indicator can be configured and is clearly visible when you use different colours. I don't mind the Caps Lock indicator, which is next to Esc, it's clearly visible and near Caps Lock (in fact, I notice it's on sooner). The keyboard is great for gaming and for work. For my part, I didn't expect to be this satisfied and I can recommend it.
