You cannot adjust half and one hour. Whatever it says 2-4-6-8 hours, etc. I bought it wrongly because there are ones from China, either analog or digital, with the desired times. Also, after a power outage, since the device is plugged in, it operates in the ON position, meaning it starts from the position we have set it, and this is dangerous in some cases if there is a connected device on it!

Smart tool, I bought it to automatically turn off my mother's radio when she falls asleep. I covered it with black tape and the photocell (sensor), so it works during the day as well. Perfect. I will also get one for the iron, so we don't forget to unplug it.
