Bought these because my landlord wont allow drilling into walls or woodwork, and I wanted window treatments to soften and disguise the appearance of the cheap, rusted metal blinds in my apartment. The magnets adhere to the outer assembly of the blinds and the rods are strong enough to hold my curtain panels. Note that my curtains are unlined. These rods would not be suitable for heavy drapes or lined curtains, but they are perfect for sheerslightweight curtains. Very pleased with my purchase!
