Review on EIGIIS Ergonomic Trackball Handheld Wireless by Lamar Marshall

Anyone suffering from wrist, elbow or shoulder pain from using a regular mouse should definitely buy this one. Being able to freely hold it saves us from having to rest our elbows/wrists on the table - this is one of the leading causes of shoulder/elbow/wrist pain caused by improper and abnormal posture. The trackball takes a little getting used to, but it was definitely a godsend for me and has kept me in a good posture when sitting at my desk! Highly recommended!
