Wired Ergo Trackball
Ergonomic wired trackball that can reduce strain on your wrists and elbows. Thumb-operated type.
USB connection, compatible with Windows/MacOS/Chrome, silent, IR LED, tilt wheel, programmable buttons, 5 buttons, 4-step DPI switching.
Used for about 1 week, but it didn't suit me. I discarded the box immediately after opening it, so I will wrap it in bubble wrap, place it in a cardboard box, and ship it via Yu-Pack (60 size).
The bluish parts are reflections from the window and are not discoloration.
Thank you for looking.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
Good value for the price. The item works as expected and there have been no issues during use. Everything seems to function properly.
