Share your thoughts with other customers
The EIGIIS Trackball Mouse uses 2.4GHz technology and requires a receiver to be used even if the device has Bluetooth. Customers have reported issues with the mouse, such as the roller ball falling off, poor battery life, and issues with the wireless transmitter. However, customers with hand injuries found it useful while recovering, and some found it a good alternative to the laptop trackpad. The mouse has both advantages and disadvantages, and it is suggested to look for a version with better quality if the product is of interest.
