The Vancer BT.L Gretxa is a wireless ultra-lightweight gaming mouse that feels well-built and is very light. Its body is perforated with weight-saving heart and diamond-shaped cutouts, and it has two side buttons on the left. Its ambidextrous shape is suitable for all grip types and nearly all hand sizes. However, it's slightly too small for extra-large hands using a palm or claw grip and too large for small hands using a fingertip grip. It connects wirelessly with its USB receiver, but you can also use it while connected with its charging cable. Performance-wise, it has impressive click latency, a very low lift-off distance, and you can adjust the CPI by increments of 50 within a broad range.
Our Verdict
The Vancer BT.L Gretxa is very good for office and multimedia work. It feels well-built and has a comfortable, ambidextrous shape. It connects wirelessly with its USB receiver, or you can use it with its charging cable. You can reprogram all of the buttons on the top of the mouse using the customization software. Unfortunately, there's no Bluetooth connection option, and the software is only compatible with Windows. Also, the scroll wheel lacks L/R tilt buttons and doesn't have a free-scrolling mode.

The Vancer BT.L Gretxa is excellent for FPS gaming. It has great click latency, feels very well-built, and has an ambidextrous shape suitable for all grip types and most hand sizes. However, it's slightly too small for extra-large hands using a palm or claw grip and too large for small hands using a fingertip grip. It also has mouse feet that glide very smoothly and, despite being a wireless mouse, a surprisingly good quality paracord-like charging cable. Performance-wise, it has a very low lift-off distance, and you can precisely adjust the CPI by increments of 50 within a broad range.

The Vancer BT.L Gretxa is decent for MMO gaming, but it doesn't have nearly as many side buttons as a dedicated MMO gaming mouse. That said, you can reprogram all the buttons on the top of the mouse using the customization software. It feels well-built and has a comfortable, ambidextrous shape suitable for all grip sizes and most hand sizes. It also has impressive click latency, a very low lift-off distance, and you can adjust the CPI by increments of 50 within a broad range.

The Vancer BT.L Gretxa is an excellent ultra-lightweight gaming mouse. It has great click latency, feels very well-built, and has an ambidextrous shape suitable for all grip types and most hand sizes. However, it isn't ideal for extra-large hands using a palm or claw grip or for small hands using a fingertip grip. It also has mouse feet that glide very smoothly and a surprisingly high-quality paracord-like cable for a wireless mouse. Its lift-off distance is also very low, and you can precisely adjust the CPI by increments of 50 within a broad range.

The Vancer BT.L Gretxa is a great travel mouse, but it's bulky and may not fit in most laptop cases. Nevertheless, it connects wirelessly with its USB receiver and feels very well-built. Its ambidextrous shape is suitable for all grip types and most hand sizes. It also has onboard memory for custom settings and a storage compartment within the mouse for the USB receiver when it's not in use. Unfortunately, it doesn't have a Bluetooth connection option.

Compared To Other Mice
The Vancer BT.L Gretxa is an excellent ultra-lightweight gaming mouse with a perforated outer shell design. Its shape is similar to the Finalmouse Ultralight 2 - Cape Town, though the Vancer is somewhat larger. Rather than the more commonplace honeycomb-shaped cutouts found on the Ultralight 2 - Cape Town and other mice with honeycomb shell designs, the cutouts in the Vancer's body are heart and diamond-shaped.

The Logitech G PRO X SUPERLIGHT is a better ultra-lightweight, wireless gaming mouse than the Vancer BT.L Gretxa. The Logitech is somewhat lighter and has mouse feet that glide more smoothly. It also has a higher maximum CPI and somewhat lower click latency. Its customization software is compatible with Windows and macOS, while the Vancer software is only compatible with Windows. The Vancer has a more flexible charging cable with a USB-C connector, compared to the Micro-USB connector on the Logitech.
The Endgame Gear XM1r is an excellent, wired ultra-light gaming mouse, while the Vancer BT.L Gretxa is a great wireless ultra-lightweight gaming mouse. The Endgame Gear has a more flexible cable and mouse feet that glide more smoothly. It also has lower click latency. On the other hand, the Vancer is marginally lighter and has a dedicated CPI button behind the scroll wheel.
The Razer Viper Ultimate is a better wireless gaming mouse than the Vancer BT.L Gretxa. The Razer has better quality feet, a somewhat higher maximum CPI, and lower click latency. You can assign a HyperShift button that enables a secondary layer of controls, and it has two additional side buttons on the right side, making it a better choice for left-handed users. On the other hand, the Vancer is marginally lighter and feels sturdier. It also has a marginally lower minimum CPI, though this is unlikely to be useful for most users. Both mice are suitable for all grip types and most hand sizes, but the Vancer is slightly more accommodating to large-size hands using a palm grip.
The Razer Viper Mini and the Vancer BT.L Gretxa are ultra-lightweight gaming mice with comparable performance. The Razer is a wired-only model and marginally lighter. It also has better quality mouse feet and lower click latency. You can also assign a HyperShift button to enable a secondary layer of controls. On the other hand, the Vancer connects wirelessly with its USB receiver or wired with its charging cable. It has a wider CPI range, a more precisely adjustable CPI, a lower lift-off distance, and a more consistent sensor. Both mice are suitable for all grip types for at least one hand size. However, the Vancer accommodates more hand sizes altogether.
The GLORIOUS Model D and the Vancer BT.L Gretxa are ultra-lightweight gaming mice that weigh the same and have comparable overall performance. The GLORIOUS is a wired-only model and has a right-handed shape. It has a more flexible cable and better quality mouse feet. On the other hand, the Vancer connects wirelessly with its USB receiver or charging cable and has an ambidextrous shape. It has a wider CPI range, a more precisely adjustable CPI, and a lower lift-off distance. It also feels sturdier.
The Logitech G502 LIGHTSPEED is a versatile, full-featured wireless gaming mouse, while the Vancer BT.L Gretxa is an ultra-lightweight wireless gaming mouse. The Logitech has a thumb rest and four additional programmable buttons. You can also set a G-Shift button to enable a secondary layer of commands, and the scroll wheel button has L/R inputs and free-scrolling mode. Performance-wise, it has a higher maximum CPI and a more consistent sensor. Its software is compatible with Windows and macOS, while the Vancer software is only compatible with Windows. On the other hand, the Vancer is significantly lighter and has a marginally lower minimum CPI. However, this is unlikely to be useful for most users.
Test Results
The Vancer BT.L Gretxa has one small RGB zone under the CPI switch behind the scroll wheel that isn't customizable and serves primarily as an indicator light. It displays a constant color that changes according to the battery level. When you cycle between CPI settings, it flashes a custom color three times to indicate which setting you've selected. There is a button on the bottom to toggle this lighting on or off.
If you're looking for an even lighter, more premium option with a similar low-profile shape, check out the Razer Viper V2 Pro.
Advertising material for the Vancer BT.L Gretxa claims a battery life of 69 hours for gaming and 336 hours for office work. However, this isn't something we test.

The polling rate options on the Vancer BT.L Gretxa are 125Hz, 500Hz, and 1000Hz.
You can program all of the buttons on the top of the Vancer BT.L Gretxa. There are two buttons on the underside of the mouse which you can't reprogram. One of these buttons cycles the polling rate settings, while the other button adjusts the lift-off distance and toggles the RGB lighting on or off.
Update 12/08/2021: We updated the firmware for the Vancer BT.L Gretxa to version 3370_20210812 which added a debounce time setting in the software. We set this debounce setting to its lowest value (4ms) and retested the latency multiple times to ensure consistency. Doing this yielded much lower click latencies than our previous results (21.5ms over its wireless receiver connection and 20ms wired.) Given the new results, we've updated our score for this section from 7.1 to 8.3.
