It took 3 people to install, with great difficulty. The dimmer stopped working properly a few months into owning it and I didn’t think to buy “insurance” on a lamp of all things. For a few months I had to spend on average 15 minutes to get the dimmer to display any light. It was so sensitive. It seemed that the light would briefly turn on if I held the dimmer by “pushing” it in. Now it doesn’t work at all and I was quoted $115 to fix this problem. No thank you, already sunk way too much money on what is now a gigantic paper weight.
