If I could give a big fat 0 I would!! Please read do not purchase from this company under any circumstances, the mini plug in heater was in a broken box no instructions no receipt.Alarm bells rang when I plugged it in noisy as anything kept cutting out. Think this had been a return from someone else.These are from some dodgy company in china who defraud as many people as they can. They need to be held accountable so I have dealt with my bank I cancelled through my bank but they managed somehow to get the money. Awful
