I'm very disappointed in these panels that specifically stated that they are room darkening and you can see right through them. I understand the final sale and no refund policy but it also states that it's only refundable if defective and in my opinion they are defective because they do not block out light whatsoever and no costumer support to contact . They are cheaply made which explains the price but if they are suppose to be room darkening then they should let them be returned. Not happy with them at all. They should have said sheer panels.
They are so thin I checked to see if they sent me the wrong ones. The only darken the room a little, about as much as any ordinary curtains. I tried them behind my Ikea panels but it was still bright even with two layers of cloth. I will be sending them back.
