I got two panels for my boyfriends room since he works at night and sleeps during the da. He says they work great and have helped him sleep a lot better. 
These curtains look really good, I'm not a huge fan of suede but they look really good. I did think they would be thicker, but maybe it's just as well they're not? They still block out light though. Overall in really happy with the purchase, I need to get two more soon!
