Review on Stay Cool Anywhere With DISONCARE 60H 4 Insulin Pen Cooler - TSA Approved Medication Travel Cooler For Diabetics And EpiPen Carrying Case With Medical Tag by Alicia Jones

Let me just say that i put the blue bottle in the freezer and the stainless bottle in the fridge overnight. I also had a test vial of water in fridge.Next morning took temp of water (38f) and put it all in stainless bottle and went to work, leaving it on kitchen counter in a 77 degree house. When I got home, 11 hrs later it was 54f and ice bottle was thawed. In contrast, I chilled the ice bottle over night again and put water vial in fridge. Next morning I put it all inside a 24 oz yeti rambler with lid. 24 hours later, everything is still under 40 degrees and the same blue bottle is just starting to thaw.Also, the plastic bottom of the disoncare fell out of bottle.Get yourself a blue bottle to freeze and use a yeti or rtic bottle. The results are much better. Trust me.Plus you have a drink cup with you when you get near a fridge :)
