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.

Not worth it

Easy and works to hold tools

These work very well. They are adjustable so they will hold most tools. If you have a steel door or cabinet and tools, they are must have. I ordered one set and was so impressed, I ordered another
