Full Review
The MX Ergo S is the trackball I recommend to anyone whose wrist hurts after a long day at the keyboard. It’s not a dramatic redesign of the original MX Ergo — same shape, same sensor, same 20° wedge — but the two changes Logitech made are exactly the right ones, and they fix the biggest gripes about the 2017 model.
What’s New vs the Original MX Ergo
Two things, really. The clicks are 80% quieter, and the charging port is finally USB-C instead of micro-USB. That’s it. If you already own and love the original, the upgrade isn’t urgent. But if you’re buying for the first time in 2026, there’s no reason to choose the older model — they’re priced within a few dollars of each other.
The quieter clicks matter more than they sound on paper. The original Ergo’s clicks were sharp and audible across a room, which made it awkward in coworking spaces and on Zoom calls where the mic picks up every actuation. The S model’s clicks are dampened to roughly the volume of a soft mechanical keyboard switch. Your meeting partners will stop hearing you work.
The Trackball Argument for Wrist Pain
If you’ve never used a trackball, here’s the pitch: your hand doesn’t move. You move the cursor with your thumb on the ball, and the body of the mouse stays planted. For people with carpal tunnel, tendinitis, or general RSI flare-ups, removing the repetitive lateral wrist motion is enormous. The 20° tilt also rotates your forearm into a more neutral position — Logitech claims 27% less muscle activity, and while that number is marketing, the subjective relief is real.
The catch: there’s a learning curve. Plan on a week of feeling clumsy before muscle memory clicks in. Fine pixel work (photo retouching, vector design) is the hardest adjustment — most people use the DPI precision button for that and live with slightly slower targeting.
MX Ergo S vs Kensington SlimBlade Pro
The other serious trackball recommendation is the Kensington SlimBlade Pro, which uses a large center-mounted ball you control with your fingers. They solve different problems. The SlimBlade is symmetrical and ambidextrous, with a much bigger ball that some users find more precise. The MX Ergo S is thumb-operated and tilted, which keeps your hand in a more natural grip and is generally better for sustained all-day use.
If you want one device for occasional design work or share it between left and right hands, get the SlimBlade. If you want a daily driver to replace your mouse and you have wrist pain, get the MX Ergo S.
Who Should Buy This
Buy the MX Ergo S if you have wrist or forearm pain and want to try a trackball without gambling on a niche product. It’s the most polished, best-supported thumb trackball on the market, and the quieter clicks finally make it appropriate for shared spaces and video calls. If you already own the original MX Ergo and it’s working fine, skip the upgrade — the differences are real but not transformative. If you’ve never used a trackball, give yourself a week before deciding whether it’s working.
