Guided checks
Used controller check
Inspect buttons, triggers, resting sticks, rotation and supported vibration before discussing a purchase.
How to use this check
Start and stop each step deliberately. Inspect the live data, then continue. A completed step means you observed it, not that the device passed.
What the browser measures
Marks show recorded events in sequence. Empty graphs mean no matching events have been observed.
Reading the result
Keep the device connected throughout the sequence. Confirm physical labels against the reported mapping. Combine browser observations with a visual inspection, connection checks and the seller’s return conditions, rather than making a purchase decision from one graph.
Why results can differ
A browser observes events exposed by your operating system. One test cannot establish whether a device is faulty. Connection, settings, focus and browser behavior can change the results.
