The Global is basically designed for portability and versatility. Because it is smaller then the Professional model, it's great for travel; however, a person with arthritis or limited manual dexterity may not find it as easy to use as the Professioinal model. The Professional model was specifically designed to require no grasping. A person can open the drawer and simply scoop out the hearing aids. But the Global's hinged lid, closing latch, and right-angled tray sides require a grasping function.

Both the Professional and the Global can accomodate multiple sets of hearing aids, from in-the-ear, behind-the-ear, and BTE-CI's. The Professional model has a divided tray in the drying compartment, which is ideal for multiple users. Body-worn processors require more room, offerred by the single tray of the Global model.

Both models utilize the same Dry-Brik® desiccant.
