The big focus for this controller is "eliminating stick drift completely", which is achieved with special HallEffect AccuRate Technology (hence the name "HEART") and it's backed by "15 years of proven expertise in magnetic sensor measurement technology for flight simulation." Here's a bit more about what to expect from this:
"Endorsed by gamers, H.E.A.R.T. (HallEffect AccuRate Technology) represents 15 years of Thrustmaster expertise in Hall effect technology applied to flight simulation joysticks. H.E.A.R.T. provides you with unparalleled precision over time, while eliminating drift through ultra-precise magnetic sensors that measure your stick movements. Providing you with optimal control, even after hundreds of hours of gameplay."
Better yet, the Thrustmaster HEART Xbox controller features stick movements tracked to within 0.01 degree, as well as mechanical buttons that are apparently faster than the usual membrane-based buttons by 64%. There's also the ability to configure things like stick sensitivity and the two rear buttons via the ThrustmapperX software.
We'll throw some screenshots of the controller down below, which is retailing for £99.99 / $99.99. We're assuming it's wired-only based on these images, so that's something to be aware of as well.
