Great for Windows!

I have to admit I didn't get this for my car, I got it to take traveling with me for when I am a guest at a family member's house (or an Airbnb!)  I am not a morning person- especially on holiday- so morning light pouring in on me at 6am is quite unwanted.  Many people enjoy that so don't think about putting light blocking curtains or shades up to protect the non-early birds.  These are perfect-- small and light for luggage and since there are 4 small ones you can configure them to just about any window shape and it does black out the light really well.  It's not going to fit over a huge bay window or anything but very adequate for most bedroom windows, very pleased.
