[This review was collected as part of a promotion.] Got these to keep my lunch at work cold since we don't have enough fridge space. This fits my lunchbox (not a Bentgo) perfectly and doesn't take up very much room at all. Keeps my food nice and cool up until lunchtime. Also due to its thinness, it fits easily into to freezer without being annoying. Great product

My husband, our two sons, and I all use these ice packs regularly, I think we have about 12 total. We love that they are thin and fit so easily in any lunch box. We typically put one on the top and one on the bottom. These will definitely keep your meal cold until lunch time, but are not all-day ice packs, so I wouldn't recommend them if you are trying to go more than 4-5 hours. They are also great for sports, we always throw a couple in a cooler in case of injuries at any practice or game and they have come in handy more than once!

[This review was collected as part of a promotion.] It fits perfectly in my son's lunch box for school. We still have room for all of his lunch without having to decide what can't fit because of the bulky ice packs. It also stays cold longer than I thought it would with the small design.

[This review was collected as part of a promotion.] These are very slim ice packs that appear to have minimal liquid inside to provide cooling capacity. They come about half full of fluid so right away your losing all that empty space of The containers appear flimsy and manufactured with cheap materials. I was concerned they could leak in my freezer. The packs look like they can deliver the cooling capacity to chill food and/or serve as an immediate ice pack for minor sprains, etc. I put food and ice packs into my backpack and after 2-1/2 hours, the food was at room temperature. Not the cooling capacity I was expecting for this product thereby earing a 2 star rating. I also placed food in a cooler bag and added all 4 ice packs…it performed better when placed in an insulated bag. You cannot count on this product keeping your lunch cool when prepared 4 hours in advance. On the positive side, because they are so slim, they fit extremely well in small lunch boxes. This is an average product that delivers less than minimally to keep dairy products cold for anything beyond 2 hours. You may find yourself using all 4 ice packs at once to keep your lunch or dairy products cold.

[This review was collected as part of a promotion.] The Bentgo Lunch Chillers are so convenient to use! Whether you use them with the Bentgo lunch container options, or even to keep grocery items cool while you're traveling home, these slender packs do the job in keeping your cold foods cold.

Slim and stays cold. I use one for the bottom and that’s enough for my child’s lunch.

These ice packs work great and are a nice size. I use them in my lunch as well!

The chillers are ok. I wish they would stay cold for longer than four hours.

Compact and fits prep bag perfectly to keep things cold

Nice and thin last most of day. I work 12 hour shifts and took out mid day for awhile stayed cold
