Having contacted Linda in reference to another product and being very satisfied with her knowledge of the products, her very friendly and effective communication skills, I decided to purchased 3 Dahua HDW3849H-ZAS-PV. The items were delivered very quickly (10 days) after placing the order. Linda kept me updated on my order from the processing, packaging, shipping and up to the day before the delivery. The items were well packaged and received in good condition. The products were all original Dahua. I am very satisfied wth my order and the service given, that i have already placed another order with Linda... I will post an update on the new order also. Thanks again Linda....
