Awesome
I have so many of these attached to my tool box. I hang so many different things from them including my drills.
Love them and will probably buy more soon.
Well made and very strong magnets.

works, just not the strongest magnet.
magnet will hold a drill but anything much heavier it will start to slide. have on e on fridge, 2 on safe and on on garage cabinet. fridge and safe hold the least, i guess due to plastic over magnet and coating on the safe and fridge. cabinet does best but still will slide with any significant weight. holds my drills ok however.
