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 was a little sceptical and worried when I first received my balloon pump. The packaging was awfully damaged even a little wet, it was not in an amazon box, just the actual balloon pump box with a label. I tested it out briefly and it all seems to be working fine. I will give it a proper test run when I make a balloon garland for a celebration and update then if need be. 🎈
Overall happy with the product and gave 4 star review. While the driver delivered the product the items were left next to the entrance door without notification when later collected the box was opened.
