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 Don Acevedo

I was worried about the size at first but these are just right for what I needed them for. I use them to hold my grow stuff on the outside and on the inside they'll hold the scrog net in place. I also have a couple hooks holding my exhale micro bag to the inside wall. I tried using one at first but it would slide down everytime I touched the bag so now it stays right there. Some of the hooks might need to be tightened when you get them and that's just a matter of twisting the hook until it won't go any further. I like them and thought about getting some for around the kitchen area. These have many applications.
