ecozoi Stainless Steel Lunch Chillers - Ice Packs for Lunch Bags, Lunch Boxes, Bento Boxes and Coolers

UPDATE: I've bought this product multiple times as it works well. I've been in a position where these freezer packs were just wrapped in towels and placed in carry on luggage (not an insulated case). The portable oxygen concentrator for my travel companion overheated mid flight. These packs were still frozen and we managed to get the device cooled down within 5-10 mins. I put one back into the back of the concentrator bag (and it fit snuggly being so thin). It completely thawed out by the time we touched down, which is so impressive because the machine was quite warm for the rest of the flight. Still 5/5 stars, it's keeps frozen extra long! --------------- 5/5 stars: It works exactly as designed, and it's very thin. I worry when it's thawed it may be easier to dent the product (something to keep in mind if there is a chance it will be tossed around when thawed). It seems to stay cold extra long because of the metal casing. Only negative is it is heavy. It being so thin means we can put more things in our cooler. I've already bought this product multiple times because I like it so much.

These are hands down the best ice packs I have ever purchased. They last far longer then any plastic one I’ve bought in the past. They keep my kids lunch items cold for the entire day. Would buy in every size! 10/10!

Get cold fast, stay cold, keep shape, slim and compact. No more leaning tower of ice packs taking up your freezer space.

Great item, stays cold

Lovely. Completely sealed with no seam or join. I know that none of the stuff inside will leak. Safe. A bit heavier than I expected. These are steel not aluminum. Just keep that in mind.

I wanted to love these Ecozoi stainless steel freezer coolers, I really did. We use a ton of freezer coolers in our house between the kids and adults lunches, so I was hopeful that these would work well. But there just ok in my opinion. These definitely do not stay as cold for as long as the plastic gel filled ones do. These thaw much, much faster. They do work well for shorter jobs though. Like my son has lunch 3 hours after he goes to school, I would trust this for that. But not much longer. There also quite heavy and they get frozen ice on the outside of them like crazy. So while I love the idea, I think that these fell a bit short.

I use these as cold compresses and also for lunch packs. Really awesome when I have allergies and I need to calm my sinuses

I use a cylinder in my 40 oz mug instead of ice, so my drink isn't watered down. I have at least 2 sets of 4, really help keep stuff cold.

Great alternative to plastic ice packs and super thin. These keep my sons lunches nice and cold from 8 a.m. to 12 p.m. and are fully thawed by the time that he gets home. They freeze way faster than the thick plastic ones and leave plenty of space in the lunch kit.
