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.
I have used Artscape before and it is a much better product than Windowpix. This time I used Waterlines and everyone loves it. My husband says it's perfect for our bathroom window. Their Customer Service is excellent. I got a response quickly in email and also a phone call from Robert.
