A grade for energy usage, used for an hour. Bought as a gift and wasn't wanted, purchased it for my mum who has COPD, during this humid summer we've just had against her will and she's refused to use it. this Model has risen to in price to £240 since i bought it in june. It has been run for an hour while i tried to convince my mum it was worth keeping but she is very stubborn and hasn't been used since then. This item doesn't come with a proper box, and arrived in a plane cardboard box i no longer have but will ofcourse sort one out for delivery, any questions or quierys pop me a message, thank you.
