Here is a Trend Airshield that I used for years and then got the Airshield Pro. This one hasn’t been picked up for along time and when I did it was not working. I don’t ever remember this unit ceasing normal functioning so I suspect this is a battery issue or a charger issue as the red indicator light does not illuminate when I plug a battery in. I know some have modified these to put a power supply on their belt. At any rate the cost is whatever it costs to ship it. No returns. No warranty expressed or implied! PM me if interested.
