To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Excellent product. Full value for the money paid. The seller took the initiative to ensure that all the items in the combo were of superior quality, packaged it well with standard Amazon packing material and ensured that the product reached me well in advance of the scheduled date in perfect condition. A million thanks to Sia Technologies for their dedication and sincere effort in focusing upon 200% customer satisfaction. Kudos to the manufacturer Hik-Vision as well as the seller Sia Technologies.
