Very dishonest.
Unwilling to read the product manual, resulting in the product not working properly. We tried to help. But he was not willing to cooperate. And was very rude to us. Acted as if we were her servants, as if we were not worthy to communicate with her as an equal.
We didn't want to waste time with her and sent a return label for her to return the product. But all we ended up receiving were a few discarded drink bottles, not our product. She insisted that she returned the product and asked for a full refund. Not only did she complain to eBay about us and send a bad review on our product page. Also attacked us on social media by posting stories that were completely untrue.
Please do not sell anything to her.
