    Multiple leaks but they did stay frozen for a long time
  

*by K***K on Reviewed in the United States on December 1, 2019*

I followed the instructions to a T and they still leaked even after being frozen through the tiny holes. Can’t really return them because half are in the trash after leaking everywhere and half are frozen in the freezer. Good idea but poor execution. Hopefully mine was just defective or something.

### ⭐⭐⭐⭐⭐ 







  
  
    Great Product
  

*by J***R on Reviewed in the United States on September 4, 2018*

These are great. We have used them over that past couple months without issues. They really do freeze quicker than regular water and last all day long. If you work outside all day, like my husband, I recommend these. Last summer it felt like our freezer couldn't keep up with refreezing the ice packs every night. Since we have gotten these, we have not had any issues.

    Three Stars
  

*by M***R on Reviewed in the United States on April 12, 2018*

Three of my packages burst while they were freezing.Updated review: The company contacted me and sent me a replacement sheet. I didn't have any issues with this set. I use them in my lunch box and they keep everything cold ALL day! I usually pack my lunch at 7am and do not eat until 1 pm and they are still frozen at that point.
