Device fine at first. The night light can be turned off at night and flashes when there is more water in the tank. The problem that's life-span of the device. I am in my second unit in a few months, yet it serves nes night. After a few months of use steam stops coming out. I thought that LBS was a good brand, but I was wrong. not present the receipt I am twice for 30 euros in my pocket. I will try another brand.
