I have 2 and none of them work. They turn on randomly. E.g. started at 6 last night, today at 15.30 it is on again. Too bad, otherwise a good product

I join Anonymous. It works for me. If not: ask the customer service.

You have to switch it on once at the time you want to start it, then it always switches on at that time and stays on as long as you have set it (probably 6 or 9 hours).
