The main advantage of the device over controllers from PlayStation and Xbox is a more reliable design of analog stick sensors. Potentiometers in DualSense and Xbox gamepads often fail, causing "drift" – false stick deviations. The Steam Controller uses TMR sensors, which should eliminate this problem.
Gamers Nexus disassembled the device. According to their data, TMR sensors surpass even Hall effect sensors, and the operating principle is shown in 3D animation in the video.
This is still theory – real reliability will be shown over time, but even now the controller demonstrates minimal drift right out of the box and looks like a solution for those who have long complained about this problem.
Gamers Nexus also noted high repairability: the device is easy to disassemble and repair. Among major manufacturers, there are currently no analogues with such a level of convenience.
Additionally, the long battery life and low latency are praised. The downside is the price: the Steam Controller, which will be released on May 4, will cost $99.
