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 analyzes reviews to verify trustworthiness.
Well, I think my sister's going to hate me for this gift, but my brother in law will get a kick out of it. Seems like a great and funny gift idea for a new dad! Will be a few years before he can really use them, but chances are when it comes to that point, my niece is going to hate me too!
