Love it!! It’s huge, larger than I expected. Wasn’t hard to put together. I recommend two people work on it together, but still can be completed by one person. Crystal knobs came in the box with the lights and I believe the metal knobs are just the standard that comes with it. Although it comes with lights, I prefer warmer tone lights. So I replaced them with smart lights that can connect with my Alexa (Much more fun to play with). Overall I am happy with my purchase!!
