This is my third lamp. 
I bought two as a set initially and set them up. The one on my side of the bed didn’t really work well turning onoff. The sensor is really poor quality. I didn’t get a chance to use my fiancé’s on his side of the bed. Finally using that one too and it’s not working as well as the replacement. Trying to return all, please. None of the sensors work right. They get stuck on or stuck off. The sensors are such poor quality. It’s a shame since I love how they look.
