What this site provides

Device Test Toolbox provides free, browser-based tests and information to help you check whether parts of your device — such as its screen, camera, microphone, keyboard, speakers, mouse, touchscreen, gamepad and connection — appear to be working. It is provided for general information and personal, non-commercial use.

Use the tests as-is

• The site and its tests are provided “as is” and “as available”, without warranties of any kind, express or implied.
• You are responsible for how you use a result — for example, whether to keep, return, repair or make a warranty claim about a device.
• Do not rely on a single browser test as the sole basis for a purchase, return, repair or warranty decision. A manufacturer, retailer or repairer may require its own diagnostics.
• Only grant camera or microphone permission when you start a test that needs it, and only on a device and browser you trust.

Acceptable use

You agree not to misuse this site, attempt to disrupt it, use it in a way that breaks applicable law, or present its results as a certification, professional inspection or manufacturer diagnosis. Do not use test tones at a volume that could damage hearing or equipment — keep volume modest, as the speaker test itself warns.

Availability and changes

Tests may be added, changed or removed, and the site may be unavailable from time to time. These terms may be updated; the version posted here at the time you use the site applies.
