Neat, lightweight radio - but the transformer hums,
This review is from: Roberts Elise DAB FM RDS Digital Radio - White (Electronics)
As other reviewers have said, this is functional, no nonsense mains-operated radio.
It has an inclined top, which means that the buttons are easy to see and operate from a chair. The presets are clearly marked and in a row. Also the on/off button is obvious and a little red light says whether it is "on" or not.
I have tested it and found the reception (in Central London) to be fine on all the main stations.
My only concern is that when the radio is switched off, the transformer makes a continuous high-pitched hum. I can hear it now and it could get quite irritating. This hum ceases when the radio is turned on.
There is an italicised paragraph in the instructions: "The mains socket used for the radio must remain accessible during normal use. In order to disconnect the radio from the mains completely the mains adaptor should be removed from the mains socket outlet completely". So, as others have said, I guess it is using electricity when switched off. I don't know if this is true of other radios too. Where I want to install it, I can't get at the mains socket easily to switch it off, so this is a problem. The transformer is also quite big - 4cm deep by 8cm long, about the size of a large three way adapter.

nieges d'autan says:
If it is turned off at the electricity socket it is disconnected from the 'flow'. They put this in because in many european countries they do not have on/off switches on the mains socket, so to disconnect it you have to unplug it. However it is true that all transformers are using electricity as long as they are connected to a live main - so TURN THEM OFF AT NIGHT; they can overheat which will shorten the life of the appliance.

Such transformers are designed to be able to be on all the time so there is no overheating issue with a transformer left permanently switched on. There is some nonsense in the media (and even from DECC) that transformers left "charged" consume electricity and we will save the planet if we switched them off. If you're only going to do one thing today to limit global warming, leave this one out and do something that will make a difference, such as not using the car to get a paper.
