These lamps for our den side tables are perfect. They are not the primary source of light, but are so great for a side tablereading lamp. The touch part works no matter where you touch it. Making operation very easy. Two USB ports on opposite sides of the lamp allow for multiple devices. Set up a charging station and can charge any of our most used devices on each table. ONLY problem we had was getting the lampshade on. Took us a bit to figure out it was inside out. Just remember the shiny part goes on the INSIDE. LOL
