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.
It arrived today. The kids were thrilled with the size. We inflated it immediately and filled with 1000 ball-pit balls. 5 hours later the top layer is completely deflated. Unfortunately my husband threw out the packaging while I was away at work or I would otherwise return it.
On average I would have given it 3 stars as we were happy with the height and size but given that it deflated on the top level with no obvious holes within 5 hours, it lost points when reflecting on the cost.
