Techni ice

I think its not worth the effort Krakka , its better to use the water in a strong plastic bottle and freeze it trick - this also reduces damage to food from ice being to cold.

The only place we use our Tech Ice now is if going out to a BYO or similar and we just throw a sheet over top of wine to keep it cool for next few hours.

Not sure about it going slimy but it definately absorbs smells and overall I am not that wrapped with it. Can't beat making your own ice at home or if you can get cheap bagged ice and have the room at home throw it in your freezer before use and it lasts for a lot longer.

Better than Techni Ice is a similar product called "Pak Ice" made by Medi-Ice Pak Australia ......reusable - nontoxic - non caustic -lasts 5 times longer than crushed ice , is used for medical product transport ,, will NOT absorb smells ect , wash before reuse. Most pathology pickup / transport couriers use it.

Definitely gets a slimmy feel over time, I assume it is the gel seeping through the sheet. No great problem though, give it a wipe.

I have found that they do not stay frozen for all that long, less than a day, but are handy for their ability to be "shaped" around the cooler contents. I got mine with the cooler, I wouldn't bother buying any more though. As mentioned above I would be inclined to use water frozen in drink bottles, or "home made" ice cubes.

We found that the plastic pillows of techni ice split after a while. We now do what Robin Miller suggested and find this works just great.

Bought several a while ago and found the first use was great .. But after they had defrosted they started to ooze the chemical thats inside the pillows - yup slimey ... Now I have 8 useless packs of slimy smelly plastic pillows !!

Frozen milk bottles - much better ...

Waeco CF-50 - Better still until no power ...

My dad had this same issue, great for a while but after a few uses they ended up a bit messy.

If we do use an esky (rather than fridge) we use a couple of the 3l plastic juice containers of water that are always kept lurking in the deep freeze at home. After being frozen for anything more than a week they seem to last longer than anything that has just been frozen overnight.

The best part is that once they are mostly defrosted you can use the water so the space is not completely wasted. I would just use water ice in any conveniently shaped freezable plastic container and forget about the high-tech gimmicky stuff.

I binned the sheets I had activated and still have the other sheets sitting around somewhere and no longer use them..

I thought they were the ducks nuts when I got them as they swelled up beautifully when I followed the instructions but then they weeped the water out and when fishing they would then get the fishy water in them etc...


I just use the 3L juice bottle with frozen water in them now.. much easier to use and the ice stays solid longer and the bottles have a handle on them to boot.

Thanks for all the replies, looks like You have saved me some money. I was going to use them to line the fridge with, thinking I could run the fridge "warmer" and saving power in the meantime.

mine got slimy after use too... so i went back to

small plastic bottles... this gives me the ability fine-tune the capacity so i can always keep it full

I continue to use them but there are pro's and con's.

They should by rights last longer that is if you have a decent deep freezer to start with, easy to mould into shape, can cut into small blocks, the "slim" is safe, good to swap between freezer and fridge when space is available.

But they do "slim", split with age (never happened to me yet), more expensive than water, absorb smells.
