How to use
- 1. Press every button inside the boxPress left, right, wheel (push down), back and forward in turn. Detected buttons turn green. If your mouse has no side buttons, just skip them.
- 2. Click normally, many timesClick the button that seems to double-click on its own a few dozen times at your normal speed. Chatter can be intermittent, so a few clicks are not enough. When the time between releasing and the next press is very short, a record and a red frame appear. Also turn the wheel up, down, left and right.
- 3. Check the result and copy itSee the clicks and chatter records for each button in the table. Add a note such as the model and copy the result for a repair or replacement request, or to check a used mouse.
If you suspect chatter
- Try another USB port or another computer
- For wireless mice, check the battery or charge and where the receiver is
- Make sure the computer’s double-click speed setting is not extremely slow
- If records keep appearing for the same button only, a mouse fault is likely
For a warranty claim or repair
Warranty periods and exchange conditions differ by manufacturer and shop. Copy the result and include which button and how many milliseconds were recorded; it makes the problem easier to explain.
FAQ
Who is this for?
People whose single clicks turn into double-clicks or whose drags break off. Anyone who wants to know which button is wrong before a warranty claim or repair. People buying or selling a used mouse. Offices checking whether a company mouse is faulty.
What is mouse chatter?
A fault where one press registers as two or more. On a mouse it usually shows up as unwanted double-clicks or drags that break off.
How is it judged?
It measures the time from releasing a button to the next press of the same button. Under 15 ms (0.015 s) is faster than a finger can realistically click, so a fault is likely. 15–40 ms is suspicious, and 40–60 ms can also happen when clicking very fast. Each button is measured separately, so pressing right just after left is not recorded. There is no official standard; these are this page’s guide values.
Does a chatter record mean the mouse is broken?
It is a guide measured in the browser, not proof of a fault. If records keep appearing for the same button over several tries, a fault is likely. Try another USB port or computer, and if it is under warranty, contact the manufacturer or shop with the copied result.
Can it check drags that break off?
Hold the button down. If it is released even for a moment while you hold it, it shows up in the chatter record. The longest hold time is also shown.
Some buttons do not light up
That does not always mean a fault. DPI (sensitivity) buttons are handled inside the mouse and never reach the browser. Buttons you reassigned in the mouse software do not light up either. Some browsers do not pass the back and forward buttons to the page. If other buttons do not light up, it may be a fault or a connection problem.
The back or forward button takes me to another page
After you press any button once, this page stops back and forward from leaving the page (so the record is not lost). In some browsers the back and forward buttons do not reach the page at all.
What is the polling rate?
How many times per second the mouse reports its position to the computer. Move the mouse quickly inside the box to see an estimate. Browser and computer settings can make it show lower than the real value.
Does it work with a laptop touchpad or a Mac?
You can check that clicks and scrolling respond. Touchpad clicks depend on the computer’s settings, so the chatter check is meant for external mice. Two-finger scrolling shows more wheel counts. Apple’s Magic Mouse has no wheel button and no back or forward buttons, and depending on your Mac’s settings, a right-click may be counted as a left click.
