The clock works wonderfully! The animal sounds are clearly visible! the only thing that bothers a little, is the lack of cover for the batteries! There, someone had written that do not match the voices with the time! I say this only: Read instruction manual! when pressing the red button on the back, move each time the votes to 1 hour! to the to undo simply proceed according to manual! all batteries out - Set clock to 11:50 - batteries back in and the animal voices are again properly!
