The freezing time may be a consideration, as they need to be frozen before use. While they can hold cold temperatures for several hours, the duration can vary depending on the external temperature and the items being cooled. Some users might find that they need multiple packs for longer trips or larger coolers. Additionally, while their portability and ease of use are significant advantages, the packs' design is somewhat limited in terms of shape, meaning they may not fit as snugly in all types of lunch boxes or cooler configurations.
