Why the MX Ergo over a cheap trackball
For a thumb ball, the MX Ergo is simply the best one. The wireless is solid, I've never had connectivity issues, and it doesn't randomly go to sleep and make you wiggle it awake like the cheap trackballs do. At its current price but worth it, and you can run it wired if you're paranoid about wireless.
That random-sleep problem is mostly a super-cheap-trackball thing. Logitech and Kensington just don't have it, which is a big part of why stepping up is worth the money.
What I liked
- Rock-solid wireless connection
- No random sleep/wake nonsense
- Adjustable tilt angle
- Wired option if you prefer
What to know
- At its current price
- Thumb-ball takes adjustment if you're new
- Heavier than a normal mouse
- Single-device pairing at a time
Common questions
Does it randomly disconnect or sleep like cheap trackballs?
No, that's mostly a bargain-trackball problem. Logitech and Kensington don't have it.
Can I use it wired?
Yes, if you'd rather not rely on wireless.
