Trust Bayo review

Rest those wrists with this cheap and mostly cheerful ergonomic mouse, the Trust Bayo, a bargain alternative to the Logitech MX Vertical.

Our Verdict


Rest those wrists with this cheap and mostly cheerful ergonomic mouse.

Ergonomic wireless mice that use a more upright position aren’t new, but their relative rarity has tended to mean they demand a high price. However, the Trust Bayo costs just $40 and offers the same core feature set as most such mice. Is it a bargain alternative to the Logitech MX Vertical and Logitech Lift?

Starting with the most important aspect of any such mouse, the Bayo’s shape is indeed quite comfortable. It lacks the rubberized surface of the Logitech MX Vertical, but we still found it easy to grip and the contouring provides a pleasant, relaxed handhold.

The only way to really use mice such as this one is with a palm grip position, where you rest your whole hand on the mouse, while movements are large, and come from the wrist and shoulder. In contrast, many gaming mice rely much more on fingertip agility, but trying to use this mouse in that way defeats its purpose and results in a poor experience.

The four main buttons – left, right, back, and forward – fall correctly under your forefinger, middle finger, and thumb respectively while up top is a DPI button. Tap this with your thumb and it will cycle between five DPI levels (800, 1,200, 1,600, 2,000, and 2,400). There’s also a scroll wheel between the left and right buttons.

It’s a standard button configuration that works perfectly well, but the quality of the buttons and wheel is noticeably not on the level of more premium mice, lacking their snappy, precise feel. You also miss out on the fast, weighted scroll wheel and sideways scroll wheel of the semi-ergonomic Logitech MX Master 3, but that mouse only has a roughly 20-degree angle compared to the 45 degrees of the Bayo and 57 degrees of the MX Vertical, so it isn’t a direct comparison.

On the left side is a translucent plastic strip that will light up in an array of RGB lighting via a switch on the underside, which also has positions to turn on the mouse without lighting and turn off the mouse. It seems unnecessary to add RGB lighting to such a cheap, productivity-focused mouse, but at least there’s that hardware switch to turn it off.

There’s also a sync button on the underside in case you lose sync with the included USB adaptor. In addition, there’s a hole in which to stow the adaptor and three glide feet. However, the glides are a touch thin, so other parts of the mouse can drag on soft mouse mats, which is irritating.

Up front, meanwhile, is a USB Type-C port for charging the mouse. The area around the socket is wide enough to fit any cable, not just the included 1m cable, but the mouse won’t work directly plugged into a PC.

Battery life isn’t rated but it uses an 18650-type cell, rather than a custom unit, so replacement may be easier than with some mice if it fails.
Finally, the optical sensor tracks on most desktop surfaces (though not glass) but lacks the fine control of more accurate mice. It’s adequate for desktop duties but not for gaming or fiddly tasks such as drawing.

Trust Bayo review conclusion

For just $40, the Bayo delivers on its promise of being a cheap but capable ergonomic mouse. Its shape is comfortable, its functions all work adequately and it has basic modern conveniences, such as a wireless connection and USB Type-C charging. You’ll get much better tracking, build quality and button feel with more expensive options, but if you just want a basic, comfy mouse for general desktop work, the Bayo does the job.
