We’re upgrading again.
Starting today, all stick-drift repairs at TechRx Repair use TMR joystick modules, and our price stays the same at $50 per controller.
Here’s the breakdown so you know exactly what you’re getting and why it matters.
—
How Standard, Hall Effect, and TMR Sticks Compare
Standard Sticks (what controllers come with)
Use carbon-track potentiometers.
Movement scrapes a metal wiper across resistive pads. Over time the tracks wear, the signal becomes noisy, and drift starts.
Problems:
Physical friction
Wear from day-to-day use
Low sensitivity
Quick degradation
Calibration instability
Higher power draw than TMR
These are cheap to manufacture, but they’re the root cause of 90 percent of stick drift issues.
—
Hall Effect Sticks
Measure movement using a magnet and sensor.
No physical contact on the sensing element, so they avoid the scraping wear that ruins standard sticks.
Strengths:
Contactless
Much better durability than stock
Lower wear
Good sensitivity
Weak points:
Lower accuracy compared to TMR
Deadzone inconsistency
Temperature-based drift
Slightly higher power draw than TMR
Plastic housings that still wear
Hall Effect modules are still dramatically better than standard sticks, and anyone who already received them from us is still covered under our lifetime warranty. If those ever fail, we replace them with TMR at no cost.
—
TMR Sticks (what we’re switching to)
These use tunneling magnetoresistance instead of voltage from magnets. Movement changes resistance inside ferromagnetic layers, giving far higher sensitivity and accuracy.
Strengths:
Highest precision of the three
Best sensitivity
Tighter center return
Higher resolution movement
Very stable under temperature changes
Better wear resistance
Lowest power draw of the three
Most consistent long-term performance
TMR costs more to produce and source, but the performance gap is worth it.
—
Power Draw Comparison (simple version)
Standard sticks: highest draw due to analog potentiometer circuit
Hall Effect: lower than standard
TMR: lowest draw of all three
Lower draw = better efficiency, better sensor stability, and improved long-term consistency.
—
Price and Warranty
Even though TMR modules cost us more, our pricing stays the same:
$50 per controller.
And our lifetime warranty still applies:
If we install TMR sticks and they ever fail → free replacement
If we previously installed Hall Effect sticks and they ever fail → free upgrade to TMR
If your controller came in with standard sticks → you’re never going back to those again
No fine print, no hassle. Reliability over margins.
