I like to callout excellent customer service when I experience it. Trend Tools gets 2 thumbs up again for handling my call today wrt a broken headband on my Airshield. When I called they were busy with other calls and I got routed to voice mail. I decided to call later since I was going to be outdoors for awhile. Within 30 seconds of hanging up I got a call back from them. Did not catch the gentleman's name but he quickly set me up with a replacement at no cost. Can't beat that! Those guys are great!
