XTRFY M4 RGB Mouse Review

The XTRFY M4 is designed to be as lightweight as possible, with a honeycomb body similar to other ultra-light mice like the Glorious Model O. It's a right-handed mouse, and it has an ergonomic shape suitable for most hand sizes and grips. There's RGB lighting in several places, such as on the scroll wheel, inside the body, and along the front end; however, they're all considered as a single lighting zone. Customization is limited since there's no software support, so you can only cycle through several preset lighting effects. It's available in six different colors; our unit is the 'Retro'.

This mouse isn't ideal for portable use. It's wired, and while it isn't particularly bulky, it might not fit into most laptop cases.

It's light, but not as light as other similar mice like the Finalmouse Ultralight 2 - Cape Town or the G-Wolves Hati. There's no weight optimization to make it heavier or lighter.

The XTRFY M4's build quality is excellent. Despite its perforated body, it feels solid, and there are no signs of flexing or wobbling. There are reports from other users of a creaking noise when squeezing the mouse, but it isn't present on ours. The buttons are clicky and satisfying, and the feet are of good quality.

The XTRFY M4 is a very comfortable mouse. It's designed for right-handed use and is suitable for most hand sizes and grips. The side buttons are easy to reach, and its honeycomb design helps maintain a good grip.

This mouse is suitable for a palm grip regardless of hand size. Most people shouldn't have any issues reaching all the buttons.

This mouse is suitable for most hand sizes using a claw grip; however, those with small hands might have difficulty reaching the scroll wheel and the front side button.

This mouse is suitable for medium to large hands using a fingertip grip, but those with small hands might have a hard time reaching the scroll wheel and front side button.

The XTRFY M4 is a wired-only mouse. It you want a wireless mouse, check out the SteelSeries Aerox 3 Wireless.

The cable is very light and flexible. It does retain slight kinks, but it shouldn't be an issue for most people.

The PTFE feet are outstanding and provide a smooth glide. However, it produces a slight scratchy sound when used on a hard surface. There are replacement feet included in the box, and you can also purchase them from third-parties.

The XTRFY M4 has an optical sensor with a wide CPI range. However, there's no customization software, so you're only limited to preset sensitivity settings, which you can cycle through with the button on the underside of the mouse. There are eight different presets: 400, 800, 1200, 1600, 3200, 4000, 7200, and 16000. The LED light next to the button changes color to indicate the current setting. There's also a physical switch on the bottom to adjust the polling rate; you can set it to 125Hz, 500Hz, or 1000Hz.

The XTRFY M4 has a relatively typical right-handed button layout with two thumb buttons on the left side. Unfortunately, none of them are programmable since there's no software for customization. The button above the scroll wheel is only for cycling through the various RGB lighting effects.

The mouse wheel is pretty basic. It's incremented, and each wheel step is well-defined, but there's no infinite scrolling and no L/R inputs. The wheel click feels a bit tight and requires a fair amount of force to press.

The XTRFY M4 doesn't generate a lot of clicking noise. You should be able to use it in a quiet office environment without bothering those around you.

The XTRFY M4's click latency is great. Most people shouldn't feel any delay.

Unfortunately, there's no software for customization. You can customize the RGB lighting by holding down the button below the scroll wheel or in combination with another button. Holding the top button cycles through the various lighting effects, such as spinning, cycling, breathing, or rainbow. The left-click controls the speed, and the right-click controls the color. The side buttons control the brightness. If you want a mouse that has software for customization, check out the Logitech G PRO HERO.

The XTRFY M4 is fully compatible with Windows and macOS.
