“I purchased this because I was taking a week-long road trip and needed to take my temperature sensitive medication during the trip. I could not have asked for a better outcome. I started with the frozen gel pack, but by Day 2 I had to switch to the cooling feature because it was in the mid 90s. I paired this with the power bank and carrying sleeve. The three pieces worked together very well. When I needed to leave the car, I carried everything with me. I did not have any problems with keeping the meds at room temperature, which was my biggest concern.They provide a storage capacity chart. Use it to determine whether this will fit your needs. For me, the size was perfect, but I was only carrying one injectable. This system protected my medication from the heat, which is exactly what I needed. While it is pricer than other options, I would rather have a system that worked than one that could fail. if my meds were stored at temperatures higher than room temperature, there would have been a chance that the meds could have become cloudy or worse, which means that they cannot be taken. To me, making sure that the medication is protected from the heat is extremely important because the replacement, if I could obtain any, would be very expensive. Taking the chance that the meds were still alright even though they were exposed to extreme heat is not a chance that I was willing to take.”
