My only complaint is that I had bought a lamp and then about 6 months later I had problems getting a replacement bulb for it. In the end, I believe I called the company and asked them to ship one to me. If I remember right, I couldn't find the replacement because they stopped making that model. (After spending quite a bit of money on the light, I wasn't happy that I ran into this problem.) I have a problem with my eyesight and I definitely like to use the Ott lamps when I'm sewing. Even though I had this problem with getting a replacement bulb, I went ahead and bought a couple of other Ott lamps for the different areas in my house where I sew.
