This is a third case I bought for my ozempic. The first 2 were from amazon. The first one was too small to hold my pens, so I had to return it right away. The second one I bought had a temp display and an ice pack. But the ice pack lasted at most 1-2 hours, and the temp wasn't accurate. I travel a lot for work, so keeping my pens cool was essential. When I stumbled upon this case, it was definitely pricier than what I would like, but I decided to give it a chance. And I'm so glad I did! First of all, it's great quality build. You can see even from the photos that really good materials are used. The case also has a really attractive design. This is by far the most beautiful case I've seen, very modern. And most importantly, the ice pack. While it takes a long time to cool it in the fridge, which is 10-12 hours, it also lasts the longest. My compact case said 8 hrs but lasted about 10 hours. This matters because its not only the duration of the flight I need to be thinking about, but also the time it takes to get to/from the airport, going through security, waiting to board or baggage claim, and so on. So it's the flight + extra 3-4 hours just for the logistics. And all this time, the pens need to stay cool. This case really delivered on that front, I finally don't have to stress about the temp problem anymore. I'm very happy with my purchase!
