I have two a table model and a floor model. My floor model was tall and had a arm which adjusted up and down and side to side. The lamp was not but about 6months old and the arm broke. The store said to bad, I contacted ott and they replaced my lamp even tho I could not find the receipt. They mailed me a lamp of my choice in the same price range are I could have the same one. I chose a different lamp and I like it but not as well as the old model. The lights are awesome would not be able to see without them. The company stands behind thier products.
