Of the three brackets, only one had a knob (the clear part) that had melted and become burrs, but it seemed like it could be attached, so I tried attaching it. Leaving aside whether it was okay or not, it was possible to attach it, so I didn't contact them, but it looks painful to remove it... so I gave it a minus star. I couldn't bring myself to buy the single color one because I was worried that my young children would get it dirty, but I think this one is good because the dirt doesn't seem to stand out so much. If I could have my way, I would have been happier if it let in a little more light. But I'm satisfied with the balance between the price and the functions I wanted!
