Good, but a better legibility would not be bad

As an alarm clock but it is hard to use me: If you were to lie with the head at eye level with the clock, the numbers are hard to detect, the same applies to a location above eye level. Cause: The clock is (unfortunately!) Slightly tilted backwards!
Best viewing angle (= best readability): an angle from above, with a height difference between eye and clock of about 50 cm.
As an alarm clock wg. the readability max. 1 star: Each alarm clock with classic pointers is because better !!
