"My typical work day requires a lot of heavy lifting, pulling pallet jacks, plus handling a lot of power tools on construction sites. Metal rings just add an extra hazard I don't need on the job. I love my FLEX Ring and forget I even have it on while working and leave my ring on all the time now."- Dillon
