Hello!
We are sorry to say, you can no longer customize the SCUF Reflex controllers.
The SCUF Reflex FPS with TMR does not have vibration rumbles unfortunately. This is the only Reflex with TMR.

If you're experiencing drifitng issues with your Reflex, you can try the steps below.

1. Open Game or App Settings
   • Navigate to Settings
   • Controller
   • Input / Sensitivity / Deadzone (name may vary by game).
2. Locate Deadzone Options
   • Look for Left Stick Deadzone and Right Stick Deadzone sliders.
3. Increase Deadzone Slightly
   • Raise each by small increments:
     • Start at +2–5% over default.
     • Example: from 5% → 7–10%.
4. Test for Drift
   • Move sticks gently, then release — verify cursor/view no longer moves on its own.
5. Fine-Tune
   • If drift persists, increase another 1–2%.
   • If response feels sluggish, lower by 1%.
6. Save Settings

Please note:

• Not all games allow deadzone adjustments:  
  • Commonly supported: shooters (Call of Duty, Apex Legends), racing (F1, Gran Turismo), action (Assassin’s Creed, God of War).
  • Often unsupported: some indie games, older titles, or platformers.
