From the reviews that I have read, the Airshield Pro has some known issues with the headband breaking. I bought mine last October and has broken twice already. I will admit, their service has been great, and the send out a new on immediately, however that does not prevent the inconvenience of being down for a week or so. The last headband, I only used it three times before it broke. Apparently Trend knows about this. After spending $400 you would think that it would at least last a few years.
I have looked at some headbands for just face shields and they look more rugged. Anyone tried to retrofit one of those? Is there a better aftermarket design? Hopefully Trend comes out with a more rugged design. I don't think I am the only one with this issue.
