Model overview based on user reviews
The A4Tech OP-330S is a wired optical mouse that is well-suited for office work. Users appreciate its classic design and affordable price. The mouse features a rubberized scroll wheel that prevents slipping and a long cable that provides ample reach across a desk. While the material quality is generally liked, some users note that the plastic legs are not Teflon, leading to visible fingerprints. Additionally, it may slide on certain surfaces. Despite these minor drawbacks, the mouse is considered a reliable choice for everyday use, with quick response times and no noticeable lag.
