From short to tall people the Cloud Nine C989M is extremely diverse in universal usability. Several types of keyboards, even ergonomic keyboards, have 5-10 degrees of positive slope from either front or to back. These types of keyboards put a lot of strain on the wrists causing pain and possibly carpal tunnel issues. THE C989M has zero degrees of slope on the exterior angles and gradually increases to 14 degrees in the middle creating a perfect slope for the most essential wrist positioning. The 8-inch cable between the two sides allows the user complete separation ranging from a small footprint to a large. This type of ergonomic design relieves ulnar deviation which can be extremely painful.
