If you like the design of the MX Master line, but would prefer a more gaming-oriented mouse, the Keychron M6 is a nice alternative. While the M6 doesn’t have Logitech’s advanced gesture controls or soft-touch exterior, it maintains the dual-mode scroll wheel, horizontal wheel, and general ergonomics while adding a 4,000-Hz refresh rate and shaving off almost half the weight of the 3S at only 78 grams. However, some small issues of build quality and a loss of functionality make this a less-than-ideal choice for most users—the dual-mode scroll wheel rattles during use, and the mouse feels lightweight to a fault. The higher-performance model’s wireless receiver requires a USB-C cable to connect to a device, which is a lot less convenient for laptop users compared to the low-profile dongle included with the 1,000-Hz model (and most other mice today).

While you can realistically transport any of the mice on this list in a backpack or computer bag, I was impressed by just how compact the Keychron M4 is. I could easily slip it into a laptop bag or jacket pocket without any issue, and I even used it as a travel mouse for quite a while. While the shape isn’t great, or even good, ergonomically, I found the claw grip quite comfortable even during prolonged gaming sessions. However, it isn’t good enough that I would recommend it to anyone for daily use on a desktop setup unless they want the lightest mouse possible. The only real complaint I had with this mouse was the dongle: The 4,000-Hz model comes with a receiver shaped like a tiny keyboard with a USB-C port on the back, which meant I needed a cable to connect the receiver and a flat surface to place it on. Meanwhile, the 1,000-Hz model came with a simple USB dongle that could plug into the side of a laptop.
