Unfortunately does not ring!

I have read the reviews before ordering, thinking that this is certainly a great egg timer, given that they are also not very cheap. Well, unfortunately I was wrong. The package arrived a few days later than previously announced. Well, so you have to expect in the Christmas season.
What is much worse: the timer does not ring at the end, unfortunately, is something obvious here defective. Too bad, it was actually intended as a Christmas present. Now I can start walking and looking at the last few days before Christmas replacement. This timer I send definitely back!
