I was very worried when I received my item and noticed it had a foreign plug. Silly me didn't even think to look at the kind of plug it has! Luckily each of them came with a US adapter and I was able to plug them in pretty immediately. They look AMAZING! Not only are they nice to look at but in total darkness the bulb is incredibly bright. The sensor is extremely sensitive and varies the output depending on how much light is in the room which is fantastic. Highly recommended, I love mine.
Can't believe that this product is being sold at Amazon. The build quality is so pathetic that it seems the bulb will slide off on its own. The bulb however lights well and responds to ambient lighting conditions pretty smartly and promptly - can't complain about that. However, as I said, the build quality is a shame and is not worth $2.00. Potential buyers beware!
