I am the Communications Director for a large church (750 average). I use the radios purchased from this web site quite often. I have made several purchases within the last few months preparing for a large scale production. One order was considered lost after shipment. After speaking with the CSR, they replaced the order, upgraded to the next available radio in stock. Without addition expense on my part. I was able to complete a conference schedule without interruption. Thank you for your support. I have made a few recommendations to others within the last few weeks since then.
