NICETOWN Blackout Curtain Liners for Sheer Curtains, Cold Heat Light Noise Blocking Liners with Rings: Easy to Open and Closed, Thermal Liners for 84 inches Long Curtains, 1 Pair, 50" x 80" Per Panel

They work as intended. Left is covered right is not covered in the pic. One panel out of 2 packs of 2 the width did not line up w/ the others.

Summer in Texas has been especially brutal this year! Years ago I added blackout curtains to certain spots of my house and left other areas with sheer curtains to allow natural light in. Now, I used these blackout panels to add to all remaining windows! Oh man, the difference, I wish I took pics! My formal dining room had sheers and the natural light was great till this year! Now with these panels the night light stays on all day and night in the dining room...it got that dark in there! These are fantastic! I'm back to buy more!!!

Upon receiving the liners I was a little skeptical with the grommets, but I looked at other reviews and how to use them and it worked out. I do notice a difference with the liners. If you need to cut the sun from beaming in, give these a try. Beats ordering all new curtains.

Buying blackout liners is way better than having to buy new curtains!!! This worked perfectly to block out the light in my toddlers room. I wish I had thought of this sooner. Excited to see if this helps him sleep longer now that the light won’t be coming through the closed blinds and closed curtains with new blackout liners! I bought the 50x92.

They are blackout curtains. I would prefer them to come in wider width so you can use just one rather than needing 2 on an ~50'w curtain panel but it's easy enough to install 2, you just need to ensure they overlap when drawing your curtains at night otherwise you may get sunlight peeking through.They are good value for money.

I have an 8' window that faces west, so when the sun starts to set, my living room becomes a sauna and it's impossible to see the TV! I ordered two packs of the grey-white 50x84 2-packs to get four panels, and the coverage is perfect. They are not 100% blackout, but VERY close. Some reviews mentioned the lighter color being less light blocking, but the lighter color looks better from the outside in my opinion, and potentially also reflect a bit of extra heat, instead of absorbing it.The fabric is pretty luxurious and thick, I was expecting it to feel and look much cheaper. I initially thought the binder clips these come with were a little silly, but they worked really well behind my grommet curtains — you literally can't tell they're there. The only thing I don't like about these is that the way they attach to the curtain rod makes it a little harder to pull the curtains to and fro, but this probably isn't an issue if you can connect them directly to a curtain instead of the rod.

These are wider than I've used in the past and I really like that. They're thick and good quality.

These are amazing! I don’t like any light at all when I sleep and these do a great job. Light still peeks out the top somewhat but otherwise helps so much!

Cumplen con la función de bloquear la luz, eso si para colgar sobre una cortina no se me hizo práctico ya que perforaría la cortina existente que en si es para lo que yo la ocupo, también trae la opción de colgar que fue lo bueno y pude adaptarla ya que no quería perforar la otra cortina, tengan en cuenta su colocación como consejo.

The heat coming through my patio door curtains was scorching hot until I added these blackout liners. Now you can barely feel any heat seeping into the house. Great way to keep your home cooler in the summer.

These work great and we’re one of the few white black out curtains I could find.The only thing is the panels are super thin haha.So I had to use two PER curtain.They are like 2.5 feet wide and regular curtains are like 5 feet wide.I mean I caved and bought them because they really do work! Just be aware or order more.

I ordered these as my daughter's dorm room is bright in the morning from the sunrise. When I opened the package, they looked and felt great. I hung them up over my living room window to test them out, and the sun still shone quit bright through them. I put my hand behind them, and I could see my shadow. Unfortunately, these will be returned as I need something that will block out more light.

It blocks out almost 100% of the sunlight. It improves my sleep a lot
