Nice looking and practical. Somewhat difficult to put together. One receiving washer's thread was bad so I couldn't screw a screw in all the way. I tried to back it out but it stripped so the screw was stuck and sticking out. 
Wayfair customer service was helpful and contacted the manufacturer who eventually understood the problem and sent a replacement.
I would make sure every pair of washer and screw fit perfectly outside of the unit before putting the washer in.
