Was looking for a vicks diffuser for my snuffly son (Thank you school germs!) when I came across this. It's a nice light that changes through 7 different colours and you can lock it on one colour. It also steams tap water with no filter required or you can add some essential oils to help your little one's breathing when they have a cold or just plain water steam to help dry skin and lips now it's coming into central heating season. It shuts off the steam when the water runs out and its a mains electric plug so no batteries. Was thinking of getting some cinnamon or pine oil for a bit nearer Christmas to be festive too?
