I used it for about a year. I'm selling it because I wasn't satisfied with the interior design shortly after purchasing it and replaced it with something else. There are no scratches or dirt, and it has been used for a short period, so it can be used for a long time to come. Personally, I found the dimming function to be very useful. It was convenient to be able to finely adjust it for different situations such as meals, light work, office work, and studying. You can also set two default settings. I will pack the shade and the electrical parts separately with bubble wrap, put them in a cardboard box, and ship them safely.
