I saw this timer with someone, it was practical and original and bought us three pieces of it. Each has / had another problem. The first broke off after a year a piece of the retaining clip, the second ever dropped the battery cover, making the device ran out. The third bounce keys and the sequence display does not work well, so that one can not tell if the device is now running or not. The first two I could make it through a Bastelstunde of two to one. This is now the only remaining viable of the three, but looks after three years already plentiful worn out. The cheapest quality.
