These curtains were ideal for 2 of my bedrooms. I wasn’t sure what to expect as they were pretty cheap but they got the job done. They are specified as room darkening, which they do to some degree but I already had blinds up so they are good enough. I bought two colours and I will say that the charcoal ones aren’t very dark at all - more of a mid grey. 
So if you’re after a decent pair of curtains for a very good price then I would recommend these. I’m happy.
