It seems to me like this product is always out of stock. Of the ones I have received and been able to use. They work as advertised and hold an incredible amount of weight. It is very easy to put them on and off, but once they are latched down, you could not remove them by hand without bending the hooks I would like to have a few more boxes to use in my steel building.

Magnet hooks you need!

I have been using these all over our shop and helps keep chords, tools and other items off the floor and more organized. I like the ease of the magnet, and it looks like. Built to last. I wish they were not so expensive.

Little pricey, but worth it

Very nice product. Creates a clean look on my fiances night stand rather than having everything all over the place. I like the little compartment with the door, its nice for putting things out of sight. The coin compartment is nice as well. The curve of the bottom makes it easy to get the coins out. I do think its a little pricey for what it is, but i still feel it was worth it to organize the clutter.
