Our Verdict
The Bytech BY-MS-WS-120 is disappointing for work. It works as a plug-and-play wireless mouse without any compatibility or connectivity issues. It also has an accommodating, if small, symmetrical shape. Unfortunately, it has mediocre build quality, lacks side buttons, and has no software to adjust its settings. It also lacks features commonly found on work mice, like a free-scrolling mode.

The Bytech BY-MS-WS-120 is passable for casual FPS gaming. It has a small, symmetrical shape and is lightweight, so it's easy to move quickly. Unfortunately, its raw performance is inadequate for competitive gaming, as there's a perceptible delay between your inputs and when they occur on-screen. The mouse also has mediocre build quality and mouse feet that don't glide across mousepads or desks smoothly.

The Bytech BY-MS-WS-120 has poor raw performance. It has disappointing click and sensor latency and a very low 125Hz polling rate. This limits the rate at which sensor and click latency reports can be sent to your computer, which can result in choppy-looking cursor movements, particularly if you use a high-refresh-rate monitor.

Popular Mouse Comparisons
The Bytech BY-MS-WS-120 is a basic, inexpensive wireless mouse. It gets the job done if you just need a cheap mouse and don't care much about build quality, features, or performance. However, for only a few dollars more, you can get a name-brand option like the Logitech M317 or the Logitech M240. Both feel significantly better built and are likely to last much longer.
