We touched on savings above, and now it is time to delve deeper. Just imagine how much time you could save by taking food from home instead of looking for a restaurant, parking, waiting for an order, and finally eating a meal that is often not particularly healthy. The same applies to looking for a store to grab an energy bar from. The more stuff you have with you, the faster you will travel to your destination. As far as money is concerned, it is clear that homemade food is cheaper than a meal at a restaurant. Food savings can get impressively big in the long run. The cost of maintaining a cooler is also low, as you only need to stock it with ice. Zero energy consumption results in fuel savings. The device itself is very cost-efficient.
