Although roughly constructed, they are well put together and look very nice. I used these to fight fluttering echoes, placed them on the back wall of my room. It helped greatly with higher frequencies and room still didn't felt too dry. Works really good. The finish is a bit rough, but given the price, totally justified. Good buy.
