I have a chance to buy a Trend Airshield Pro for $200. It's new in the box at an estate sale bought about a year ago and never used due to purchaser getting sick and passed away. I've read on this site about them and reviews online. The reviews and opinions are all over the map. I just watched a video from Woodcraft of a man using one to turn a project at a lathe and when he took it off it was fogged up. Just looking for some opinions of people that own one. thanks. Right now I'm using a half mask respirator under a Bionic face shield, I'm getting by fine other than kind of hot in some summer days.
