Logitech K780 Multi-Device Wireless Keyboard

I've really liked this keyboard for my WFH setup because it lets me switch using bluetooth between my laptop and my personal PC just by pressing the button on the top left, but after using it for 2.5 years, one day the left Alt button became wobbly and loose. The issue is worst when I hit the bottom part of the key, in which case it raises the top part and ignores the keystroke, making it pretty annoying to Alt+Tab, among other things. I looked up solutions online (apparently this problem occurs for others around the 2+ year mark too), and tried to replace the left Alt button with the right Alt button since I really wanted to continue using this keyboard, but the issue was that some plastic in the keyboard base itself was broken, not the scissor switch. I like membrane keyboards and the quietness of scissor switches, but the fact that they are difficult to repair and can be rendered unusable due to a tiny bit of plastic snapping -- something that becomes more and more likely over time -- means I'll be looking into a quiet mechanical keyboard instead.
