## Questions & Answers

**Q: How long do these stay frozen for ?**
A: Mine have stayed frozen for approximately 9-10 hrs. I left food in the cooler,which was well-insulated, and it which was still cold when I got home. This was kept in office setting with temps in room in the 70’s.

**Q: When you say that this item is colder than ice, what does that mean? ice can be cooled to any temperature unless i'm mistaken. a rock can be 18*f.**
A: Karæthon's answer is correct.  Freezing or melting overcomes the  "latent heat of fusion" which is about the same heat as is required to raise the temperature of (for example) liquid water by almost 80°F, or frozen water (ice) by about 150°F.   So an ice pack in a cooler will spend most of its time at it's melting point. Once it's all melted, the subsequent temperature rise will be very quick.

**Q: Are these reusable?**
A: They are reusable.  There is an initial "just add water" setup to change the dry powder to gel, then you throw them in the freezer for several hours and they are ready for use.

**Q: If I were to use two of these together, would I have similar cooling capacity as one of the medium-sized packs?**
A: Not positive of that but I am amazed at how well these things work.  4 of them keeps a large cooler super cold.

### ⭐⭐⭐⭐⭐ Review
*by B***A on 28 March 2019*

Brilliant!! I used these packs to keep pumped breast milk cold overnight in a cool bag and in my nappy while out and about. I have also used them to keep a dozen or so bags of breastmilk frozen while travelling. I use 2 of the packs overnight in a cool bag and the breastmilk is ice-cold - cold enough to put straight into the fridge. I use 1 pack in the front zip section of my backpack-style nappy bag that holds 3 bottles of breastmilk. The great thing about these packs here is that they are soft when room temperature so I mould them to fit into the small front compartment and then freeze - normal rigid ice packs don’t usually fit. I have used all 5 in my cool bag to keep my breastmilk bags frozen on 2 trips lasting 3 hours - they were still frozen solid at the end of both trips!! When I first read the info on these packs, I was worried that the breastmilk would freeze if a bottle was in contact with them. Luckily this has not been the case as you can control the amount of cooling with the number of packs. These cool packs have taken away so much of the hassle of expressing and storing breastmilk - one less stressor as a new mum!!
