Its design is sleek and compact to conserve valuable desk space but it stays right where you put it because of its nice heft and special undercoating. The U.are.U 4500 radiates an attractive blue glow that provides an unobtrusive presence in low light environments and also ensures that it does not compete with alarm colors in settings such as healthcare.
