Review on 12-Pack MHDMAG Magnetic Hooks: Super Strong Key Holder With Neodymium Rare Earth Magnet For Indoor/Outdoor Use With BBQs, Grills, Curtains, Fridges, Keys, And More by Dennis Long

Update 5/2019 - I gave these hooks another try on a recent cruise and they worked GREAT! The walls in our cabin, the bathroom and stateroom doors were all places we hung these clips. They were perfect for hanging our swimwear, exercise clothes, pool bag, etc. The key seems to be attaching them to a larger, very solid metal surface.I purchased these primarily for travel, unfortunately they didn't work for me. In a hotel room the only thing metal that was strong enough for the magnet to hold onto was the desk legs. Once it magnetized to the legs I couldn't even hang a small purse from it. The purse was only about 3 pounds, no where close to the 18 pounds listed. Nice idea, but not big enough or strong enough.
