Love the idea of this. I bought it as on of my husband's birthday presents and it works ok. I wish it had at least one more magnet in it. If the magnets were a little bit stronger I think it would work that much better. But it does what it needs to. It keeps those screws and bolts close. However if you aren't careful you can knock them loose. That's why I wish there was another magnet or stronger magnets in it. Overall it is good, but does leave a little room for improvement.
