Overview

The Razer Basilisk V3 Pro and the Logitech G502 X Lightspeed and G502 X Plus are comparable gaming mice. Each uses optical switches, USB-C charging, and a similar ergonomic design. The design features include a thumb rest, multiple thumb-side action buttons, a sniper button on the front for switching to a lower DPI, and free-spinning scroll wheels.

The Logitech G502 X models lack RGB lighting as standard. The G502 X Plus is identical to the standard G502 X black model apart from its RGB lighting.

Specifications and Connectivity

The Razer Basilisk V3 Pro offers higher specifications. The Logitech G502 X offers two additional programmable buttons and longer battery life. The G502 X has an LED indicator that signals DPI changes and low battery.

Design and Ergonomics

Both mice share a similar shape. Each has textured grips on either side, easy-access side buttons, and PTFE feet, including on the underside. Both fit the hand well and keep most of the hand off the desk through the thumb rest.

• Razer Basilisk V3 Pro: The matte finish provides grip. The dock on the underside can be removed. A swappable cover, available in the premium version or as an additional purchase, enables Qi wireless charging. The Razer magnetic dock is sold separately. The base model does not include this option.
• Logitech G502 X: The front DPI button can be removed, rotated to face the other direction, or replaced with a cap. The Razer mouse does not offer this option.

The G502 X side buttons, placed next to the left mouse button, are easy to press unintentionally.

The G502 X is well suited to right-handed users. Left-handed users are better served by the Logitech G502 X Superlight, which has a more symmetrical shape.

Neither mouse is particularly light. The author did not find either weight burdensome, although the author has used lightweight mice in recent years.

Charging

Both mice support wireless charging through optional accessories:

• Razer Basilisk V3 Pro: Qi charging through a swappable cover, used with a Qi charging mat or the Razer magnetic dock.
• Logitech G502 X Lightspeed and G502 X Plus: Logitech PowerPlay system, using the PowerPlay Mouse Mat and the included puck attached to the underside of the mouse.

Both mice have USB-C ports for wired charging. Neither wireless charging option is included with the base models.

Software and Customization

Both mice offer extensive software customization.

• Logitech G502 X: Five onboard profiles.
• Razer Basilisk V3 Pro: Hypershift, which assigns one button as a modifier to access a secondary layer of actions.

Scroll Wheel

• Logitech G502 X: The wheel can be switched between a tactile mode and a free-spin mode through a button press. The wheel has a metal finish and is considered to spin longer.
• Razer Basilisk V3 Pro: The Synapse software can set the wheel to switch automatically to free-spin mode when the user scrolls quickly. Pressing the button behind the wheel toggles between tactile and free-spin modes. The author considers the Razer implementation less effective than the Logitech wheel but notes that it is unusual.

The Razer Basilisk V3 Pro's adjustable resistance wheel, located on the underside of the earlier Basilisk Ultimate, has been changed in this model.

Conclusion

The author prefers the Logitech G502 X for its premium design, longer battery life, and overall finish. The G502 X is also the more affordable option. The Razer Basilisk Ultimate, the higher-end model in the earlier comparison, is more expensive but offers wireless charging. The Razer Basilisk V3 Pro has the stronger specifications. Users who prioritize specifications and the top tier of Razer's range may prefer the Razer mouse.
