The XTRFY MZ1 – Zy’s Rail is an excellent ultra-light gaming mouse designed by YouTube mouse reviewer Zy Rykoa, AKA Rocket Jump Ninja. Its honeycomb design makes it very lightweight, but it feels sturdy and doesn't creak or flex. Its shape appears to be symmetrical, but it has a slight right-handed curvature. This shape won't be for everyone, but it's ideal for a fingertip grip for all hand sizes and suitable for a palm grip for smaller hands. We don't recommend using it with a standard claw grip, but some users report that it's well-suited for a modified claw grip. Unfortunately, it doesn't have software for remapping buttons or customizing preferences, and it only has eight default CPI presets you can cycle through directly on the mouse.
Our Verdict
The XTRFY MZ1 – Zy’s Rail is only mediocre for office use. It has no wireless capabilities, and it doesn't have companion software for remapping buttons. On the other hand, it feels very well-built and is fully compatible with Windows and macOS. It's ideal for a fingertip grip for all hand sizes and suitable for a palm grip for smaller hands.

The XTRFY MZ1 – Zy’s Rail is a mediocre mouse for MMO gaming as it doesn't have nearly as many side buttons as a dedicated MMO mouse, and you can't remap any of its buttons since it doesn't have companion software. That said, it feels very well-built, has great click latency, and has a very flexible and lightweight cable. It's ideal for a fingertip grip for all hand sizes, but you may also find it comfortable using other grip types, depending on your hand size.

Compared To Other Mice
The XTRFY MZ1 – Zy’s Rail is a collaboration between XTRFY and YouTube mouse reviewer Zy Rykoa, better known as Rocket Jump Ninja. It has a sturdy but lightweight honeycomb design and solid sensor performance similar to other recent XTRFY releases like the XTRFY M42 or the XTRFY M4 RGB. Unlike those mice, however, it has a very unusual shape. While it's ideal for a fingertip grip for all hand sizes, it'll likely take new users some time to get used to and ultimately won't be for everyone.
For more options, check out our recommendations for the best mouse, the best gaming mouse, and the best wired mouse.
The Razer Viper Mini and the XTRFY MZ1 – Zy’s Rail are both excellent wired gaming mice. The Razer has a lower minimum CPI, a more precisely adjustable CPI, much lower click latency, and companion software for customizing settings and remapping buttons. On the other hand, the XTRFY has a more flexible cable and a lower lift-off distance. Both mice are ideal for a fingertip grip for all hand sizes and a palm grip for smaller hands, but only the Razer is recommended for a claw grip for smaller hands.
The XTRFY M42 and the XTRFY MZ1 – Zy’s Rail are excellent ultra-light wired gaming mice with honeycomb designs. The M42 has significantly better click latency and modular back panels. It's ideal for all hand sizes using a fingertip or claw grip and smaller hands using a palm grip. On the other hand, the MZ1 has a more flexible and lightweight cable and is ideal for a fingertip grip for all hand sizes, though it's also suitable for a palm grip for smaller hands.
The G-Wolves Hati HT-M Classic Edition and the XTRFY MZ1 – Zy’s Rail are both impressive ultra-light gaming mice. The G-Wolves has a more precisely adjustable CPI, a much lower click latency, and software for customization and button remapping compatible with Windows. It's well-suited for all grip types and nearly all hand sizes. On the other hand, the XTRFY has a somewhat higher maximum CPI, a more flexible cable, and better mouse feet. It's ideal for all hand sizes using a fingertip grip and suitable for small hands using a palm grip.
The GLORIOUS Model O and the XTRFY MZ1 – Zy’s Rail are excellent ultra-light gaming mice. The GLORIOUS has a more consistent sensor, a much lower click latency, and companion software for customization. It's ideal for all grip types but best suited for smaller hands. On the other hand, the XTRFY feels sturdier and has a higher max CPI. Its shape is best-suited for a fingertip for all hand sizes or a palm grip for smaller hands.
The GLORIOUS Model D and the XTRFY MZ1 – Zy’s Rail are excellent ultra-light gaming mice. The GLORIOUS is a bit lighter, has a more precisely adjustable CPI, and has much better click latency. It also has companion software for customization and button mapping. On the other hand, the XTRFY has a wider CPI range and a lower lift-off distance. The GLORIOUS is well-suited for all grip types and nearly all hand sizes, while the XTRFY is best suited for fingertip grip and suitable for smaller hands with a palm grip.
Test Results
At first glance, the XTRFY MZ1 – Zy’s Rail appears to have an ambidextrous shape, but its left side is slightly more curved. It also has a semi-translucent plastic body with honeycomb holes designed to keep the mouse as lightweight as possible. There are RGB zones inside the mouse, in the scroll wheel, and in a strip that runs along the front and sides. Lighting customization is limited as there's no software, but you can cycle through presets with buttons directly on the mouse.
The build quality feels excellent. Despite its honeycomb body, it feels sturdy. There are no signs of flexing and no rattling when shaking the mouse.
Update 12/13/2021: We had incorrectly identified this mouse as ambidextrous, as at first glance, the mouse appears to be symmetrical. After retesting the mouse and examining its curvature, it's clear the left side curves inwards slightly more than the right, favoring right-handed users.
The XTRFY MZ1 – Zy’s Rail has an unconventional shape. It's quite slim in the middle, narrows towards the front, and has deep finger grooves on both the left and right-click buttons. It has a fairly flat, low profile, a relatively short length, and a blunt back end with a tall hump. This mouse is ideal for a fingertip grip, though some may find it comfortable to use with other grip types.
This mouse uses the new Xtrfy EZcord Pro, which feels more flexible and lightweight than the Xtrfy EZcord found on the XTRFY M42.

XTRFY also has detailed instructions on their website for changing the polling rate, lift-off distance, and debounce time. The polling rate settings are 125Hz, 500Hz, and 1000Hz.
The XTRFY MZ1 – Zy’s Rail has a scroll wheel that feels precise. It has pronounced notches and a rubberized coating that makes it easy to control.
The XTRFY MZ1 – Zy’s Rail has no software, but you can adjust RGB lighting settings, CPI, polling rate, lift-off distance, debounce time, and bind the button behind the mouse wheel to F11 using combinations of button presses and switch settings directly on the mouse. XTRFY has detailed instructions on its website on how to adjust all settings.
Note: XTRFY have released a firmware update that lets you to bind the button behind the mouse wheel to Page Down instead of F11.
