Full check
Every check for your device, one after another. Stopping partway or skipping a step is fine.
How is this different from the single checks?
It runs the same tests. What it adds is not letting you forget one. On a device you just unboxed you don't yet know where the fault is, and picking checks one at a time is how one or two quietly get skipped. Here the order is fixed and the step counter stays in view, so finishing the flow means nothing was left out.
Before you start
- Set aside about ten minutes. Leaving the page loses your progress.
- The webcam and microphone steps ask for browser permission. Video and audio are handled inside your browser and never uploaded.
- The speaker step plays a tone. Turn the volume down a little first.
- Starting the flow asks which device you are on first. Keyboard and mouse need a laptop or PC and touch needs a phone or tablet, so you only get the checks that fit what you picked.

While you run it
- The counter at the top shows which step you are on.
- Pick a result for a step and the 'Next check' button opens up.
- Skipping works, but going through the whole flow is better.
- If something looks off, the single-check page goes into more detail.
Computer and phone
The flow assumes a computer. Open it on a phone and the keyboard and mouse steps become a short note instead, while everything else runs normally.

- Laptop keyboard not working — how many keys tells you why
- Laptop camera not working — start with proof, not drivers
- Microphone not working — when only they cannot hear you
- How to check laptop speakers — crackle and a dead side
- Mouse or trackpad not working — frozen, jumpy, dead clicks
Where do the results go
Nowhere. They're gone once you leave the screen. There is no account and no server storage. So if you want to keep what you found, write it down while the results are still on screen.
This isn't a verdict
ReturnCheck never tells you a product is defective. It helps you write down what you saw and heard, and stops there. The call — and the conversation with the seller — is yours, which is why you pick the result for each step yourself.
