Approximately 10% of the population is reported to be left handed. Whilst being left handed doesn't often cause any concerns, when it comes to ergonomic mice it unfortunately does. Ergonomic mice are designed for either the right hand or left hand. Few are able to be used by both hands. Luckily, we stock a range of left handed ergonomic mice for left handed people, which will help relieve your wrist, hand and forearm pain.
