Was in need of strong magnets. The description and title say they’re strong and heavy duty but I’ve used magnets less than half the size of these and they were wayyy stronger. I bought the 15x3 mm ones. I gave them 2 stars cause they are okay magnets if you don’t need a real heavy holding weight. I just don’t think they should be advertised as "strong” or "heavy duty” but the price for 50 isn’t bad.
