Cons

  • Foam edges may lift over time, particularly with increased drag.

  • Installation can result in misalignment issues, especially if the minimum door gap isn't considered.

Bottom Line

If you need a more robust solution for larger gaps or specific flooring compatibility, exploring additional products might be worthwhile.
