I can finally invest in shirts that don't have a button collar again! After trying these at work I can honestly say these are awesome. Heck, I would have used these on my dress uniform when I was still in the military. I cannot say they would stand up to a rough environment but its perfect for office work, Magnet is surprisingly strong though, I would trim the plastic covering back a little. My work is mixed in both sitting at a desk and high movement, so I did test them for a week straight with no issues. The only time the magnet dropped was during a time I was adjusting my collar. Worth the small investment.
