Cooler Shock Reusable Ice Packs for Cooler - Long Lasting Cold Freezer Packs for Coolers and Lunch Boxes - Cooler Ice Packs for Camping Gear, Fishing, Road Trips, Beach Must Haves

I’ve been using these ice packs for about 3 months, and they’ve been holding up extremely well. The quality is impressive, and once prepared correctly, they work exactly as advertised. Important tip: Make sure to follow the directions closely. These do not work immediately. The instructions state to freeze the packs for at least 8 hours before use, which is necessary for best performance. I work at a hospital and pump breast milk during my shifts, so keeping my milk cold is non-negotiable. These ice packs keep everything ice cold for over 12 hours, which honestly impressed me. The night before work, I freeze two medium-sized packs, then place them in my cooler bag in the morning. I lay them flat while freezing so they are pretty slim, which makes it easy to stand them upright in my cooler later. The packs are very slim and space-saving, which I love—but be aware that the corners are quite sharp, so handle them carefully. The bag itself looks sleek with its black color and feels very high quality and durable. As for setup: the directions are clear, but the process is a bit particular. I’ll admit I had my husband help me because precision matters here. One key step is measuring 28 oz of water and letting it sit for a few minutes to release air bubbles (this is important!). You pour the water in using the included funnel, do not add the silicone plug yet, close the screw cap, and shake vigorously to mix the contents. Then you remove the cap again and gently squeeze out excess air before sealing it completely. If you carefully follow the instructions, you’ll be totally fine. Overall, these ice packs are reliable, long-lasting, and well-designed. I plan to purchase a larger size for our big cooler for beach trips. Highly recommended for working parents, breast milk storage, travel, or anyone who needs serious cooling power.

I recently took my full size refrigerator out of my business, but still wanted to get my Amazon fresh groceries delivered at work, since my home isn't in the delivery range. That also means the food is already thawing for an hour before it gets delivered. So, I needed better cooler bags and reusable ice packs that could stay cold for 10 hours before getting the food delivered, and then hold up for another few hours before getting the food home (another 3-4 hours, so the ice stayed mostly frozen for almost 14 hours in these bags). I bought these ice packs after reviewing every product on Amazon, and I got the Titan insulated bags. I avoided ordering things like ice cream or frozen waffles, because I've noticed those don't arrive frozen by the time they deliver the groceries. I mainly ordered frozen meals, mini pizzas and refrigerated stuff. The food was still frozen when I got home! The only thing that thawed were some frozen french toast sticks (I took stuff like that out of their boxes because I figured it would help keep them cold better if they had direct contact to the ice). The refrigerated stuff was plenty cold still too. These ice packs get so cold that it almost burns your hand to touch them. They stay cold for a lot longer than my thin blue ice packs of various brands. They freeze in a nice thin shape, seem to have excellent build quality, and are a great size. I wanted more small ice packs rather than one large one so I could make sure all of the food had ice on almost all sides of it. They actually weigh quiet a bit, which is probably why they can stay frozen longer than the cheaper ice packs that I have. I was really hesitant at first to get these because of the cost, and having to fill them with water myself, but I am so happy that I did! They were easy to set up and do a great job. We actually have power outages pretty regularly and I feel more confident that my frozen food will stay frozen longer with these in the freezer. When you are squeezing the air out of the pouch, after adding water, you can see the material inside the pouch is a light blue color. After it sets for a few minutes it becomes gel inside. So far only the edges thaw out after 14 hours of use. And it does seem to help if they have a full 24 hours to re-freze after use (as opposed to 12).

水を適量計って入れる作業が要るが特に困る事は無い。 ただ大きさをわかっていたつもりが想像より大きく 分厚さもあるため手持ちのクーラーボックスではそのままでは使えずに 凍らす時に折り曲げている。 Mを４つ買ったがMは一つでSを複数の方が良かったかもしれない。 まだ２つしか使っていないので残りは予冷用に使う事も考えたが 家庭用冷凍庫の場所にも限りがあるのでキャンプ前に容量に余裕のある時限定かも。 勿体無いが友人に使ってもらう事も考えよう。 用途は一泊のキャンプなので翌朝の食材も冷えたまま保存できて問題なし。 ２５Ｌくらいのボックスなら一つを曲げて入れるくらいかな 二つだと容量がかなり減ります。 ソロでＭ４つは多すぎです。

It works exceptionally, I am really happy for my purchase. I tried to find the best cost/effectiveness and this was the result, it made me discover that the lunch bags we have has bad insulation. They are exceptionally cold for a minimum of 12 hours (in bad insulation) so I'm excited to use these in coolers for summer camping. Thank you so much for making a great product that's also fun to make! No regrets for this purchase.

An und für sich eine gute Kühlleistung, allerdings ist einer der 4 Beutel ohne Gewalteinwirkung in der ersten Woche der Verwendung direkt unterhalb des Drehknaufs gerissen und damit unbrauchbar. Bei dem Preis meiner Meinung nach nicht akzeptabel. Mein Fazit daher: Grundsätzlich gut, aber scheinbar sehr fragil, womit es für den Einsatz in der Kühlbox in Anbetracht des Preises zu Riskant ist. Würde ich mit diesem Wissen nicht wieder kaufen.

Keeps cold for half the stated time Better than ice but bags are not as sturdy as the plastic counterparts

Brilliant cool box accessories, stay frozen for days not just an afternoon, well worth the money
