Is a trackball better than a regular mouse?

A trackball keeps your wrist in one place, which can ease strain from repeated mouse dragging. It is slower for precise aiming at first, so gamers and designers often stay with a mouse.

Is it really left-handed?

The listing says yes. Check the product photos before buying, because a left-handed trackball puts the ball on the right side for thumb use.

What does 4,000 DPI mean here?

It sets how far the cursor moves per ball rotation. 4,000 DPI is fast for a trackball; most users will want a lower setting for control.

Does it need a dongle or Bluetooth?

The listing does not say. Confirm the connection type and whether a USB receiver is included before you buy.

Our take on the Acer Wireless Mouse 4000 dpi Ergonomic Mouse

The Acer Wireless Ergonomic Mouse is a six-button trackball mouse with 4,000 DPI sensitivity, built for people who want to move a cursor with a thumb ball instead of sliding a mouse across a desk. It is listed as left-handed and travel-friendly, which is unusual for a trackball. Trackballs at this price are rare, so it suits shoppers who want to try the format without spending much.
