As an industrial and scientific worker, I'm impressed with the ARES 47007 set! It's fantastic, its magnetic properties stored my tools securely and made finding them simple... As a result of my tests, i determined that this item has a fantastic level of toughness. It is easy to transport and can withstand severe drops and blows without breaking! The only downside is that the magnetism on a few of the organizers was a little weak necessitating regular adjustments. overall, it's a fantastic investment for any industrial hand tool kit..
