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 bought these balloons for a kids’ Halloween party and while my husband was blowing them up they were bursting in his face! He made sure he wasn’t over inflating them but they continued to burst. Poor, poor quality and going on our experience I would strongly recommend you not to waste your money buying these balloons. We ended up binning them! I didn’t want to risk returning them in case they were sold on as I was that appalled at the poor quality.
