Logitech MX Ergo Trackball Mouse: what owners actually say
Owners love the ergonomics and pain relief, but switch failure is an inevitable and widely-discussed repair job
What owners complain about
- Microswitch failure / double-clicking COMMON
Switches go intermittent after roughly 2 years of use, causing missed or double clicks. Multiple owners report this across Logitech trackballs. The stock Omron D2FC switches (Chinese-made) are specifically called out as the weak point; some owners solder in Japanese D2F-01F replacements which reportedly last longer electrically.
- Debris accumulation in ball socket SOME
Dirt, dust and fluff get trapped in the ball socket requiring periodic cleaning. Owners pop out the ball every several months and are surprised how much buildup occurs. Described as inherent to trackball design with no real solution.
- Silent switches in newer model have shorter lifespan FEW
The MX Ergo S uses silent micro switches rated at only ~20 million clicks vs normal switches with higher ratings. If a silent switch fails, it can only be replaced with another silent switch, compounding the longevity problem.
- Rubber coating degrades over time FEW
The rubber coating wears out with extended use and renders the mouse unusable, contrasted unfavorably with the older M570's basic plastic shell that held up better over a decade.
- Roller bearings create scratchy noise FEW
The trackball's roller bearings produce a noticeable scratchy grinding sound during use, described as louder than other trackballs.
What owners love
- Eliminates pain from regular mouse use
Owners report zero shoulder and wrist pain after switching, even after years of daily use. One user went from persistent shoulder pain with a normal mouse to complete relief with the MX Ergo.
- Long-term durability of the trackball concept
Users report 3-4 years of reliable use before issues arise, with some using Logitech trackballs since 2013. The form factor itself earns deep loyalty, with owners buying second and third units.
- Indispensable for professional workflows
An architectural designer calls it an indispensable part of their daily work after 3+ years. The precision and ergonomics support long sessions of detailed work.
- Repairability empowers owners
Owners appreciate that switches can be desoldered and replaced, extending the life of the device. Community guides dating back to 2005 exist for the repair, and some owners keep bags of spare Omron switches at home.
Surprising patterns
- Owners have built an entire DIY repair ecosystem around this mouse: soldering in premium Japanese D2F-01F switches as upgrades, swapping springs from donor mice, and even using WD-40 as a temporary fix for intermittent clicks.
- X-Mouse Button Control software is strongly recommended as an essential companion, enabling trackball-based scrolling that emulates the infinite scroll of Logitech's MX Master line — a feature the hardware itself lacks.
- Multiple owners have migrated away from the MX Ergo to Kensington trackballs or Ploopy open-source alternatives after repeated switch failures, citing the scroll ring on Kensington models as a notable advantage.
WHO SHOULD SKIP IT
Buyers who cannot or will not solder should look elsewhere, as switch failure within ~2 years appears near-certain and the repair requires microswitch replacement.
