BEST Customer Support EVER!!Reviewed in the United States on May 3, 2020
Unit arrived and installed ok, seemed to work as well as I understood it, over time I learned what it was supposed to do, and well beyond the Amazon return window, I realized it wasn't working as it should. Via multiple online chat sessions we determined it was not working, but within the warranty period. As soon as I shipped the defective unit back (apparently internal rechargeable battery had failed) they cross shipped a replacement. No Fuss No muss!
