I’m still rocking my OG first gen MX Master today, 11+ years and counting of daily backpack tossing, having survived 3 MacBooks and at least 7 chargers. My only secret? I bought a $10 padded case for it on Amazon the very first day I had the mouse, and zip it in there every time before it goes in my backpack.

Everything works as new, the only thing that broke is the plastic covering the gesture button.
