Built by hand.
Signed off in The Den.
Two build paths. One standard: nothing ships until it's opened, tested, and signed off by the tech who built it. Here's exactly what happens between teardown and your front door.

TMR lifetime
Anti-drift, forever
Every controller earns its way out the door.
Every Mamba is built in The Den — by us, in-house, one controller at a time. Nothing gets outsourced. Nothing gets a "refurbished" sticker and a quick wipe-down. Here's what we won't ship without:
Diagnosed, not guessed
Every controller gets a 25-point teardown before a tech decides what it needs. We don't ship hope — we ship a fix.
Real parts. No shortcuts.
OEM thumbsticks, fresh buttons, genuine triggers — never aftermarket knock-offs. Every build is assembled one controller at a time by a tech who games on what they ship.
TMR is standard
Magnetic anti-drift joysticks on every build — Pro Restored and Mamba Custom. The only stick we trust enough to cover for life.
Live-game tested
Nothing leaves The Den until it's played in a real match. Warzone, EA FC, Rocket League — pressure tested, not bench tested.
The 25-point process.
Five phases. Twenty-five checkpoints. Every Pro Restored controller goes through the exact same gauntlet — no shortcuts for "easy" units, no exceptions for rough ones.
External Inspection
Shell & Damage
Faceplate, back cover, and shell checked for cracks, chips, and heavy wear.
Buttons & Sticks
Every button and analog stick tested for response, drift, and dead zones.
Charge Port
USB-C port checked for solid seating, clean contacts, and reliable charging.
Triggers & Bumpers
L1/R1 and adaptive triggers tested for smooth pull, even tension, and full travel.
Internal Cleaning
Careful Teardown
Opened with precision tools so no clip, ribbon, or board takes damage.
Dust & Debris
Internals cleared with compressed air and soft brushes — every cavity.
Contacts & Sensors
Boards, contacts, and sensors wiped with isopropyl alcohol.
Battery Health
Cell tested for capacity and charge cycles. Compartment cleaned.
Repairs & Replacements
TMR Stick Upgrade
Old sticks pulled and replaced with magnetic TMR modules — drift-proof, standard on every build.
Button Sheets
New conductive sheets installed for crisp, responsive presses.
Triggers & Springs
Worn springs and trigger mechanisms swapped for full snap-back tension.
Fresh Battery
Weak cells replaced with a tested battery rated for full play sessions.
Reassembly & Polish
Tight Reassembly
Every screw, ribbon, and contact seated correctly — no shortcuts.
Shell Polish
Exterior cleaned and polished for a like-new feel in the hand.
Shell Swap
Heavily scratched shells replaced before the controller leaves The Den.
Detail Pass
Seams, grips, and crevices brushed out so it looks as clean as it plays.
Performance & Final Checks
Stick Calibration
Calibrated to zero drift and smooth, even movement across the full range.
Vibration & Triggers
Rumble and adaptive triggers confirmed in a live game session.
Connectivity
Paired over Bluetooth and tested wired via USB-C for stable connection.
Final QC
Audio, mic, and every input cycled one last time before it ships.
Built up, not just bought.
Starts as a Pro Restored core. Then we upgrade what matters — TMR sticks, clicky triggers, paddles, battery — and finish it in a shell that looks like nothing on a shelf.
Start With A Restored Core
25-Point Base
Every Mamba Custom begins as a fully restored controller — same 25-point process.
Board Verified
Internals tested clean before a single upgrade goes in.
Performance Upgrades

Magnetic TMR sticks installed — zero deadzone, zero wear. Covered by our lifetime guarantee.
Clicky Triggers & Bumpers
Tactile microswitches for instant actuation — built for FPS and fighters.
Back Paddles (Optional)

Extended Battery
Higher-capacity cell option for double the playtime per charge.
Custom Shell & Finish
Shell Selection
Pick from hydro-dip, UV-print, matte, or chrome finishes on OEM shells.
Coat & Cure
Multi-coat finish cured and sealed for chip-resistant durability.
Accent Detailing
Buttons, D-pad, and stick caps color-matched to the build.
Clear-Coat Seal
Finished with a clear protective layer so the design holds up to sweat, grip, and daily play.
Den Tuning
Firmware Update
Latest firmware flashed before final assembly.
Dead Zone Zeroed
Sticks calibrated to a true center with custom curves available on request.
Trigger Tension
Trigger travel and tension set to spec for the upgrade kit installed.
Battery Burn-In
Full charge cycle run to confirm the cell holds a real play session, not just a quick top-up.
Final QC & Ship
Live Game Test
Played in a real match — Warzone, EA FC, Rocket League — before it boxes up.
