Review on Versatile And Easy-To-Install H.VERSAILTEX 4 Pack Magnetic Curtain Rods For Metal Doors With Petite Ball Finials - Adjustable Rods For Iron And Steel Places, 1/2" Diameter, Black (16"-28") by Lauren Lewis

I got these to make some curtains for our patio doors. They work great and the magnets hold extremely well. You've got to apply quite a lot of force to get them to move. That being said, they are definitely not fastened with something something more permanent.It took a bit to get my teenage son to be careful and stop hitting them with things when he goes outside. He would always knock the bottom rod loose. He's gotten much better about it now and hasn't knocked them down in close to a month. So this is something you should consider if you are planning to get them. Energetic kids, people with vision problems, and just carelessness will contribute to the magnets getting knocked loose.
