The Salt Rock itself is beautiful, but the lighting part of the lamp is non functional unless you make adjustments! It says no bulb included, but there was one. There is a hole in the Salt Rock, but the bulb, socket and cord assembly is too small to stand up in that big hole. You have to put some kind of reducer in the hole to have the bulb stand up in the hole securely. And, there is no dimmer switch as one reviewer said, it is a remote on /off switch in the middle of the cord. This Black Tai Salt Lamp is no where near as nice as the formerly available and little more expensive Variable light Salt Lamp i purchased from OS Dec 2013. Too bad they are gone, i thought this one was the closest to it, but it is not functional unless you make the adjustment!
