Frizet T 200 Freezer Blocks(4 Pcs) ~ Freezer Pack ~ Ice Pack for Ice Box, Cooler Box, Camping, Picnic, Outdoors, Cars Etc.

I was only wanted a low cost freezer block, they were delivered as scheduled, no hassle.I use them in a cool bag to bring with me when golfing to keep my drinks cold and they did the job.Note the golf reference is because we are out for 4 hours in the sun with temp, rising from low 30's, C, so they performed well.

This product must be kept in the freezer for approximately 12 hours for complete cooling. Then it is capable of keeping your foodstuff cool for 12-18 hours in a small icebox. A very good alternative to using ice - it keeps your stuff cool for longer and does not create a puddle in the icebox. Good value for money.

I didn't know anything can keep things cool for more than 12 hours. Being a working mom, I'm using it for storing & carrying breastmilk to home.I'll try for other purposes in future.

I use it to carry expressed breast milk from work. The ice pack stays in the Medela cooler bag all day and it remains pretty cold. It is good for ten hours. I use two packs.

Have been using it for sometime. Keeps the water cool for a long time.
