text: Not for the backseat, if that is what you need it for.
  
  Ok, so I heard that this could be used in the backseat for cup holders if your vehicle doesn't have them.. um. no. The fastening slots are open at the bottom, plus they are small, so lacing a seat belt through is pointless. Comes off immediately. It's lightweight so it will fly off the seat if you stop even slightly suddenly. I'm giving 2 stars because it is sturdy, lightweight, and inexpensive- but it's fastening system means it is not secure in your car.
