"I bought a pair of 516 pants and was skeptical when I saw them that they would work. One day and half days later I ordered a second pair. They were quickly named my 'magic pants', much to the amusement of friends and work colleagues. Over 10 days of wearing them the size of the inguinal hernia reduced by about 70%, coughing and sneezing no longer had me bent double to prevent pain. I did try a day without them just to see what would happen. One careless movement and the hernia started to swell. I have had my operation and no longer require to wear them but for me they were 'magic'. "
