Complete false advertising! Not blackout whatsoever! And as a shift worker I need blackout, which is why precisely why I purchased this item that clearly states blackout. 
Not only is it an incredible hassle to cue for ages at the post office during the Covid lock down to return them, but to make matters worse they wont refund my original shipping cost, nor cover the cost to ship it back to them leaving me out of pocket - even though their product that they sold to me is a lie and isnt fit for purpose! 
And on a side note they dont hang well and look very cheap. Absolute rubbish.
