Review on TREND AIR PRO Airshield Protective Face Shield by Jerry Frey

One of the few things I've had to return. Had high hopes for this woodworking item. The main problem is the filters, although I didn't have enough time to find other problems. The filters were removed after the first use. The battery instructions said it might take a few charge cycles to get the most out of the battery and after only a few hours of use I figured that was the problem. The alarm went off and the airflow decreased noticeably. I recharged it for the recommended time but the alarm still went off and the airflow decreased. I checked the filters, they seem fine. I tapped them and even tried sucking them off. They looked clean. A small pressure gauge is in place to check airflow and it didn't move at all. He has to move the small ball up the tube. During my evaluation, I uninstalled and reinstalled Filter several times to find the problem. They are very difficult to put back into use. I'm a fairly cautious person, but after the little tab on the filter broke a couple of times, it became unusable. Not that it matters because I wasn't getting any airflow with them anyway. When the filters were removed the gauge showed good airflow so it was definitely the filters. My problem is that this happened after about 3 hours of use, which I consider normal use for the average carpenter when sanding. That's my experience, and at around $60 for a set of filters, it's clearly making a comeback. By the way, I emailed support twice to identify the problem and received no response after at least a week. Conclusion: A cheap, overpriced product with poor/non-existent customer service.
