I had seen these same lamps on other websites for almost double the price, this was a great deal and I love the lamps.  They free up nightstand space, move as needed, provide three way lighting and are very attractive.  The installation took a bit of time because you need to install the bracket first but it came with all necessary screws, anchors, etc. However, it was a far less costly alternative to do it myself instead of pay an electrician to install some of the hardwired models I looked at!  The most challenging part was doing two- one on either side of a king size bed - to make sure they were the same height.  This was easier with a laser level....Plug covers finish the look and make it look professionally installed.  I was concerned it might look like a hotel room, but the design added so much to the  room and went well with my cherry wood furniture!  I was very impressed with the quality and would absolutely recommend these lamps to anyone.
