Why is my mouse cursor behaving erratically, and how can I fix it?

check the battery: As product is wireless, like all battery-operated devices, their performance hinges on the power available from their batteries. To ensure your wireless mouse continues to operate at its best, you need to check and change or charge appropriately and timely

Adjust Cursor Speed and Sensitivity: Access the mouse settings on your computer (usually found in the Control Panel on Windows or System Preferences on macOS) and adjust the cursor speed or sensitivity. Reducing these settings can often help manage erratic cursor movements.

Use an Optimal Surface: Optical and laser mice can behave unpredictably on reflective or transparent surfaces. Use the mouse on a mouse pad or a piece of non-reflective, colored paper. This provides a consistent surface for the optical sensor, enhancing its accuracy and preventing erratic behavior.

Check and Update Drivers: Remove any previously installed mouse drivers, then restart your computer. This can resolve conflicts between the mouse software and your system. For this process, go to device manager and check the driver in Mice and other pointing device

Select “Scan for hardware changes. This will allow your operating system to refresh the new hardware for plug and play.

Restart and Reconnect: Sometimes, simply restarting your computer can resolve underlying issues causing erratic mouse behavior. After restarting, disconnect the mouse and then reconnect it. Try using a different USB port, especially if you're using a USB mouse, to rule out port-related issues.

Update or Reinstall Mouse Drivers: Outdated or corrupted mouse drivers can cause erratic cursor movements. Check the manufacturer's website for the latest driver software for your mouse and update accordingly. If issues persist, try uninstalling and then reinstalling the mouse drivers.

Check for Interference (for Wireless Mice): Wireless mice can experience interference from other wireless devices. Ensure there are no strong wireless signals near your mouse or USB receiver. Changing the USB port for the receiver can sometimes help, as can moving other wireless devices further away.

Inspect the Mouse for Physical Damage: Look for signs of wear or damage, such as a frayed cable, dirt or debris blocking the sensor, or damaged buttons. Cleaning the mouse, particularly around the sensor, using a soft, dry cloth can sometimes resolve issues.

Try Another Mouse: If possible, use a different mouse with your computer. If the problem persists with a new mouse, the issue might be with your computer. If the new mouse works fine, your original mouse may be defective.

If the issue recurs, the mouse may be defective. In this case if you are an Amazon customer, please return the product to Amazon for a replacement or refund. If you bought the product from our official website, please contact our customer service:

The mouse is too small and causes hand discomfort. What should I do?

Consider Alternative Models: If your hand size is smaller than 7 inches, we recommend considering our smaller vertical mouse model, PERIMICE-519, which might be more suitable for you.

Consult a Professional: If discomfort persists despite using the correct mouse size, consulting with a healthcare provider is advised to ensure ergonomic safety during use.

Is the mouse compatible with Mac, iMac, or Linux systems?

Windows Compatibility: The mouse is fully compatible with Windows 7, 8, 10, and 11.

Mac Usage:

Although the mouse can function on Mac systems, compatibility may differ across various OS X updates. It's advisable to consult customer reviews for feedback on its performance with recent updates.

Linux and Other Systems: Compatibility requires that your system adheres to Human Interface Device (HID) standards. The mouse necessitates HID support to operate effectively across different operating systems.
