Good for the money

This is a good product for the price quality of thickness isn’t as good as others but what I expected for $11 a panel I would suggest buying it if finances are tight and you need something it helps Pictures show how much light it keeps out, specifically when the sun is shining directly into this room. Also the underside which is black.

Perfect for my needs

I was looking for something to help with the sun in my family room. I have blinds up but they do not do much for blocking the light coming in….. Trying to watch tv on a sunny day is nearly impossible with the glare. Decided on these. Fabric is soft and looks like satin. Thicker than I expected which is a plus. I got the black and wasn’t looking for a true blackout curtain. SOME sun does still shine through but I don’t want a completely blacked out room, bedroom sure, but not for my family room. These are perfect! The picture shows how all that all the light from the sun is now hitting the ceiling above instead of my tv.

Mainstays Blackout Curtain

We bought 3 different curtains; two Mainstays %26 1 SunZero. My intention was to purchase all Mainstays brand, however, my partner went to the store %26 bought SunZero. Both are great. We are using them to close off the living room while using a portable ac. It makes the room dark and hopefully works as intended. If you want blackout curtains for you bedroom the Mainstays curtains will do the job. I purchase the Walmart brands whenever possible. Their products for the home are well made and last. I will always recommend their brand!
