I have this burning chair clock run in my basement in connection with a ventilation. You uncomplainingly doing already was years in service. This was the reason to buy now a second for the Aquarium my son for me. But apparently the quality has now abated considerably. The first new timer programming was lost again. Well you say to yourself, so what can happen even once. Then I exchanged this timer with a new one. But even this loses again its program. Meanwhile, I am so unnerved that I decided to take the next one switch from another manufacturer. I can only advise against this timer ..... pity
