Overview
Held in the palm rather than slid across a desk, this Elecom Relacon uses a thumb ball to move the cursor. Ruby ball bearings support the ball, and a hole in the base lets you pop it out for cleaning. A wireless receiver and batteries are included.
Handheld use and a ten button layout are the reason to choose it for couch or standing-desk work without a mouse pad. The limit is learning the thumb control, and the battery needs periodic replacement.
Who it's for
Users with wrist strain or no desk space will use the thumb control. Gamers needing wired latency or a palm-sized mouse shape should look at standard mice.
Pros and cons
- Thumb-controlled handheld design
- Ten buttons with DPI switching
- Left or right hand use
- Easy to remove and clean ball
- Thumb control has a learning curve
- Receiver uses a USB port
Performance notes
A sensor reads the ball movement, and ruby bearings reduce friction so the ball glides. The three resolution settings change how far the cursor moves per roll. Cleaning the ball and bearing area helps tracking stay smooth over time.
