Bought in America and with an American plug this oil diffuser does work in the UK (I used a plug adapter to check). The whole unit soundlessly diffuses oil infused water and glows or cycles through a number of pretty colours. If you want to try a diffuser but not ready to buy a new expensive one, give this a go. Needs USA style sockets or a plug adapter, or process the cable with a UK version. Free to collect from CB24
