Bought this 2 months ago and since I have had it I have used it everyday. Multiple colours to select from or the light can be turned off completely. Running at full power the water lasts 24hrs and 48 hrs roughly at low power. I love this product that much that I bought one for a friend and have recommend it to other friends. Only issue and it’s tiny but when you refill the water that is in the lid spills everywhere but if you are quick you can tilt the top on its side and let the run off go back into the water container. Very happy with this product.
