Query: Problem after few weeks of use

The Norpro egg Rite timer does work, but it has a major problem with the glue material that joined the two halves of the timer. After few weeks of use we have start noticing air getting inside the timer. It is very annoying because it get harder and harder to see the indicators inside.We asked for replacement and the same thing happened again with the new timer.
