Query: Seems to work OK but counter-intuitive and poor workmanship

The timeris not intuitive to operate but,once mastered, seems fit for purpose. However within 2 weeks, the magnetic stick-on strip that bonds unit to fridge door etc fell away from the unit dropping it to the floor. Had to stick back on with Super glue! That is just shoddy manufacture
