Amazing product, really does the job as described. People commented on the air quality in my flat and the scent. It lasts up to six hours but you can adjust the timing to 1, 3 or 6 hours and choose if you want to have the mood light on or not.
I bought this product together with Top 14 Luxury Aromatherapy Essential Oils Set. The oils were good value for money but they are not the best quality. ( I have to put quite few drops to create the aroma) but you get what you pay for and 25 pounds for 14 essential oils was a great price.
Over all it scored top marks and I would buy the diffuser again , even as a gift!
