I had installed them on two balconies. Both programmers showed water leakage from the wide central plastic clamp after two years, which could not be fixed. As a result, I had to replace both...

Purchased as a replacement for the same device that worked for decades. I hope for the same lifespan. The mechanism is as simple as possible; you insert a 12v battery (flat) and choose one of the programs. For example, 1 minute of watering every 12 hours. The timer starts from the installation of the battery

The Aquano Logica Balcony Plus (or alternatively Claber 8446) is essentially the same irrigation programmer as the Claber 8444, but adapted for use on a balcony (instead of a garden), with shorter watering times:
1, 2, 5 min / 12 h
1, 2, 3, 4, 5, 6, 8, 10, 15 min / 24 h
2, 5 min / 48 h
8 min / 72 h

Very reliable, with a solenoid valve that interrupts the flow in case the battery runs out and with a very simple programming (simply select a number from 1 to 15). The only downside: the setting of the watering start time is the moment of selecting the program (and the repetitions follow accordingly) - it cannot be a different time.
