Cooler Shock 4 Mid Size Freeze Packs Screw Cap (10in x 9in)

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。

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.

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.

Bought these for a 4 day camping trip to a festival, as our usual iceblocks barely last a day. Used 4 medium packs in a 26litre Coleman coolbox, and they kept everything cold for the full 4 days. Even on the 3rd day, the orange juice was almost colder than what comes out of our fridge! The weather wasn't overly hot, but I was still very impressed with these, and recommended them to all our fellow campers

Molto caro per quello che fa . Mi aspettavo prestazioni differenti da prodotti simili che già avevo e che fanno lo stesso lavoro . Non vale la differenza di prezzo .
