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 a very low lift-off distance, and you can adjust the CPI by increments of 50 within a broad range. Unfortunately, it has high click latency for a gaming mouse, and many gamers may prefer a more responsive-feeling option.

Our Verdict

8.0 Office/Multimedia

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.

Pros
  • Feels very well-built.
  • Comfortable, ambidextrous shape.
  • Connects wirelessly with its USB receiver.
Cons
  • No Bluetooth connection option.
  • Scroll wheel lacks L/R tilt inputs and has no free-scrolling mode.
8.1 Video Games (FPS)

The Vancer BT.L Gretxa is very good for FPS gaming, but it has high click latency compared to other gaming mice. That said, it 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.

Pros
  • Feels very well-built.
  • Very lightweight.
  • Comfortable, ambidextrous shape.
Cons
  • High click latency for a gaming mouse.
7.4 Video Games (MMO)

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 a very low lift-off distance, and you can adjust the CPI by increments of 50 within a broad range. Unfortunately, it has high click latency for a gaming mouse.

Pros
  • Feels very well-built.
  • Comfortable, ambidextrous shape.
Cons
  • High click latency for a gaming mouse.
  • Not nearly as many side buttons as a dedicated MMO gaming mouse.
8.4 Ultra-Light Gaming

The Vancer BT.L Gretxa is an impressive ultra-lightweight gaming mouse, but it has a high click latency, and many gamers may prefer a more responsive-feeling option. That said, it 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.

Pros
  • Feels very well-built.
  • Very lightweight.
  • Comfortable, ambidextrous shape.
Cons
  • High click latency for a gaming mouse.
8.0 Travel

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.

Pros
  • Feels very well-built.
  • Comfortable, ambidextrous shape.
  • Connects wirelessly with its USB receiver.
Cons
  • Bulky; may not fit in most laptop cases.
  • No Bluetooth connection option.
  • 8.0 Office/Multimedia
  • 8.1 Video Games (FPS)
  • 7.4 Video Games (MMO)
  • 8.4 Ultra-Light Gaming
  • 8.0 Travel

Lighting Color RGB

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.

Differences Between Sizes And Variants

The Vancer BT.L Gretxa we tested is the Cream Matcha color variant. There are other colors available, including a Blue, Pink, and Metallic Red variant. You can see the label for our unit here.

Compared To Other Mice

The Vancer BT.L Gretxa is an impressive 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. While the Vancer has excellent build quality and overall sensor performance, it suffers from high click latency compared to other gaming mice at its price point.

See other recommendations for the best lightweight mice, the best gaming mice, and the best wireless mice.

Glorious Model D

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,  better quality mouse feet, and a much lower click latency. 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.

Razer Viper Mini

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 much 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.

Razer Viper Ultimate

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 much 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.

Logitech G502 LIGHTSPEED

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, a more consistent sensor, and much lower click latency. 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.
