SIXSIR Leverless Arcade Stick M16+ Large Slim Aluminum - Precise RGB

In this review the SIXSIR Leverless Arcade Stick M16+ is presented as a specialist controller for players who prefer button-accurate inputs over a traditional joystick. The biggest reason to consider it is its leverless layout combined with low-profile Kailh crystal switches and a rigid aluminum alloy panel, which together deliver very low input latency and a sturdy feel for lap or desktop play. It stands out for compatibility across consoles and retro platforms, and for users wanting fine directional control rather than an analog stick.

Key Features

• Leverless 4-way layout: Replacing a joystick with four movement buttons gives tighter, more precise directional input for fighting and retro games.
• Wide compatibility: Works with PS5, PS4, PS3, Nintendo Switch and many systems over USB including Steam Deck and Raspberry Pi builds.
• Aluminum alloy body: The M16+ uses a larger 30020012.5mm aluminum panel and weight-saving design to feel solid and ergonomic for larger hands or lap use.
• Low-profile switches: Kailh crystal low-profile switches with GP2040-CE reduce input latency to under 1ms and improve responsiveness.
• Custom RGB: Multiple RGB color combinations let users match the controller to their setup and personalize button lighting.
• Onboard configuration: Firmware and configuration available via web access after connecting to a PC so players can remap and update features.

Who It's For

The SIXSIR M16+ is best for fighting game players, arcade purists and retro enthusiasts who value extremely precise digital inputs and low latency over the feel of an analog joystick. Its leverless design and larger panel suit users with bigger hands and those who play on a lap or larger surface.

Casual players expecting a conventional joystick experience should look elsewhere, and anyone requiring full native support on older or niche consoles should check the manual and support site for setup steps, since some platform settings need to be confirmed before use.
