Review on Keychron K4 Hot Swappable Mechanical Gaming Keyboard RGB Backlit - 96% Layout Bluetooth Wireless/USB Wired - Gateron Brown Switch Aluminum Frame - Mac Windows Gamer PC-Version 2 by Jennifer Groom

I recommend a foam insert because the case has a lot of space and can sound muffled when typing. The connector is now USB-C, which is great. The lighting isn't very bright, but it's a good compromise for better battery life. I also recommend replacing the keycaps with PBT keycaps. The keyboard layout can make it difficult to find suitable aftermarket replacement keycap sets, as some keys are unusually sized (0, right Alt, right Control, right Shift). Delete, End and Page Down are in different places. than regular keyboards, so the keycaps will be odd height when you replace them.
