To calculate the overall star rating and percentage breakdown by star, we do not 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.
My son has been wanting some of these for his GX bottle but we couldn't seem to catch these in stock! I finally found some and ordered them on 12/18. When I opened the box, I noticed the use by date for all of them was 1/16/21 - about 3 weeks from Christmas day when I gave them to him. Amazon was very nice. They said that it wasn't the norm for the product and they would notify their supplier.
I bought the Glacier Freeze zero and my son loves them. They are convenient for a small lunch bag or gym back. We do keep them in the fridge but you don't have to. At first it seemed hard to get the pod to empty right but once we figured it out, they work just fine. They average at other stores for $8 for a pack of four to the amazon price I paid was great! We will be ordering again.
