EO were great to communicate with during my purchase. They responded quickly and communications were clear both in writing and during phone calls. Plain concise English was used to explain items and processes. The charger itself is a brilliant piece of equipment. It is compact, solidly built with a tough paint over a metal frame. It has been reliable, connects and charges instantly and is easy to plug/unplug. It quickly and easily connected to my WiFi and has stayed connected, communicating with the app quickly and reliably. Thanks for a great service & product EO.
