my old 1.8 inch lcd alarm would not work any more . I research a lot of clock , and find this 2.5 lcd . Amazon ship it in 3 day for free . my first night , I wake up 5-6 time just to see the time ! I could barely read the 1.8 inch , no problem with the 2.5 . it be bright , but for I , that a good thing . if I be not here , my wife can flip it down . Perfect !
