Query: Cheap junk. Headband breaks - big design flaw

I have gone through two of these AO/3M face shields in less than a year, under light use in my home wood shop. In both cases the cheap plastic headband has broken at one of the pivot points (where it is attached to the visor), rendering the whole thing useless. That's because there is a big metal grommet mounted in a hole punched through the band at each pivot point, which leaves very little material surrounding it to lend strength to the headband. This weak spot is very vulnerable, resulting in early failures of the product. It's just a matter of time before the torsional forces of raising/lowering the visor will snap that part of the headband. An obvious design flaw. Don't buy this - it's junk!Another 1-star reviewer here mentioned having good results with the UVEX shield. I may switch over to that model, as the reviews look promising.Uvex S8510 Bionic Shield, Black Matte Face Shield, Clear Polycarbonate Anti-Fog/Hardcoat Lens
