Key features

1. Physical recoil-control structure
   A carefully designed angle and damping mechanism helps you control how much and how fast you pull down, reducing those “I can’t hold the spray” moments.

2. No mouse firmware flashing
   All the control comes from the external device itself. You don’t need to flash your mouse, change its firmware or do any high-risk modification.

3. Simple, plug-and-play
   Connect using the included data cables and follow the order in the quick-start guide. No complicated software installation required.

4. Balanced feel and desktop aesthetics
   A hexagonal, sci-fi design with circuit-style surface details makes RainbowHand both a functional tool and a clean centerpiece for your setup.

5. Built for multiple game scenarios
   Works great with most first-person and third-person shooters, helping you train recoil rhythm and control continuous fire patterns across different titles.
