I am very pleased with this salt lamp. So far it works great. I love the fact that it has a dimmer switch on it. I don't leave it on all night though as a night-light simply because I don't like leaving any more electronic things plugged in during the night than are necessary, otherwise I would keep it plugged in and turned on 24 hours.
But it looks really nice sitting on our kitchen counter. I plug it in first thing in the morning and turn it off before we go to bed. It's a conversation starter for anyone who sees it who doesn't have one.
I would buy another one from here and I may just to have an extra one on hand to give as a gift or to have one to put in a guest room or something.
