Kona Blue Ice 2 Pound Ice Packs for Coolers - Long Lasting Design - Refreezable Reusable Cooler Ice Pack (2)

Warning: these are not kitten proof! My 5 month old kitten had the zipper open in no time! It didn’t work for my purposes but my son uses it all the time and loves it. He says it stays cold a long time!

Bought these and a cooler to transport a cooler from a Ga to DC. The cheesecake made it still frozen. Great purchase. Some assembly required. Becomes a beautiful blue color. Both fit beautifully side by side in the cooler I bought. Very sturdy.

Works great and lasts long. Perfect for camping with items you don’t want saturated or a beach day.

I read some of the reviews about this product leaking, but decided to purchase it anyways. The 1st thing I did after filling it, was shake it to mix it, but also shake it to see if it would leak. Sure enough it was leaking, but I figured out very quickly why. Edge of the opening is unfinished and is very raw looking. I fixed the issue simply by taking a razor blade to the unfinished edge. Afterwards, I tightened the cap as tight as I could get it, shook it again and it was fine. It is now in the freezer waiting to freeze.

Why did you pick this product vs others?: From reviews I thought they'd be good. For years in my soft cooler I've been using 1 Ozark Trail ice pack that keeps my drinks cold all day in my truck. I put 2 of these plus 4 of their slim ones in my cooler, with drinks, and left it sitting on my kitchen table. Within 2-3 hours the slim ones were melted already and by hour 6-7 my drinks were warm. I wouldn't recommend this brand at all. I contacted the seller days ago but haven't heard anything. It's now a month later and I'm still using these with terrible results! They come out of the freezer cold but after being in the cooler for 2-3 hours, one side will be cool and the other is warm. I've tried everything I can too make these work like they supposed to but they're junk. Even when adding real ice with them they don't stay cold. I've still not gotten a response from the seller either. I'll never buy another product from this brand!

Stays cool for a great amount of time! It's still cold when I come home after a 14hr shift! Absolutely referring my friends!

These are heavy duty ice packs! The spout opening is small but they come with a paper funnel which works OK for pouring in the water. The blue powder stuff mixed well with moderate shaking (just until my arms got tired). I like the opening in the middle; it makes it easy to grab these out of the deep freezer. I also bought the huge, flat style of these ice packs. I use all 4 in my average size chest style cooler when I'm making grocery store runs in the summer. I can fit 3 gallons of milk and other cold items and these 4 ice packs in there just fine. I am good with spatial dimensions and when I'm done packing up the cooler, everything is set just right and snug. I like this brand of ice packs so well, I may buy more and gift them to family for Christmas!

They stay cold longer.

stays cold longer than an ice block and are re-usable. love em.

We use these for camping and they’ve been great. Very durable.

Awesome product.. the caps do not seal 100% after you’ve filled and shaken them.. but I’m thinking they’ll most likely always be at least half frozen so there’s little chance a future leaks.. cheers!

purchased these for road trip to Florida. They stayed cold together for over 8 hours. Great to be able to store them on a shelf when not in use.

Poor design. Caps leak. I tightened them as much as I could by hand but they still leak. I ordered others brands at the same time that came filled and sealed and have had no problems with those ones. I’m going to try to glue the lids on and see if they still leak so I can get some use out of them. If that doesn’t work they will be thrown out.
