Ordered these to darken 3 windows in my toddler's room.  I was a little nervous to order pre-cut blinds online, but the 38 inch width fit PERFECTLY into each window.  As with all blackout blinds, there is a sliver of light that peeks through the sides, but I expected that, and they still provide a dramatic darkening effect.  These look good, seem high quality so far, and I was impressed by how quickly I received them (since ordering custom sizes from blinds.com etc. can take months).  We're definitely noticing the room stays warmer at night now that these are up, and the cordless feature is a no-brainer for nursery/kids' rooms.  Would order again, and would definitely recommend!
