I purchased the smallest size option, black. Looks nice. Very narrow opening and it is necessary to clean with vinegar inside and out to remove residue. Wear gloves! Easy to install. You can’t pick the perfect height as the rods only have so many configuration options, but I found it to be sufficient. Notice that the bulb housing is likely not perfectly straight and I found it to be impossible to get it to be straight. If you need perfection, maybe don’t purchase these fixtures. The black piece that holds the glass up is easy to cross thread and hard to get tight without risking breaking the glass.
