Just had a full knee joint replacement and this helps keeping ice up to my ice machine so much easier. Particularly when my mobility is limited. Even keeps the water ice cold for 6hrs at a time.
When Ice Changes State, the Environment Changes Too
As traditional ice absorbs heat, it transitions from solid to liquid. That liquid water doesn’t disappear — it collects at the bottom of the cooler.
Now instead of a cold solid sitting next to your food or fish, you have cold water pooling around it.
Water transfers heat differently than air. It also creates direct contact exposure.
In short: The cooling method shifts from “solid ice contact” to “submersion in meltwater.”

Cooling Without Creating Water
Reusable ice works differently.
Instead of changing state and becoming water inside your cooler, the cooling medium remains sealed.
Heat is absorbed.
Cooling still occurs.
But the surrounding environment stays dry.
That means:
- No pooled freshwater
- No shifting from solid cooling to water submersion
- More predictable internal conditions
The temperature may be similar — but the behaviour is different.
That’s the key distinction.
Cooling is heat transfer
Melted ice water changes storage conditions
better suited for multi-day trips and frequent use than buying ice repeatedly
Why This Science Becomes Practical
The difference between melting ice and sealed cooling matters most when:
- Cooling is needed for extended periods
- Food or fish sits directly in the cooler
- Clean storage conditions matter
- Ice replacement isn’t convenient
Understanding how heat and water behave helps explain why some people move away from disposable ice for repeat use
Ezee Freeze was designed around this principle — to deliver cooling without introducing meltwater into the storage environment.
FAQ's
Is reusable ice colder than traditional ice?
Both cool by absorbing heat. The difference lies in how they behave during use, not just starting temperature.
What is latent heat of fusion?
It’s the energy absorbed when ice changes from solid to liquid. This is why melting ice can remove significant heat.
Does sitting in melted ice affect food?
Prolonged exposure to pooled water can change storage conditions. Many storage systems aim to keep food elevated above melted ice water.
Is reusable ice less effective than ice because it doesn’t melt?
Not necessarily. Cooling effectiveness depends on total thermal capacity and insulation. The key difference is environmental behaviour during use.

Absolutely love them in all aspects. In drinks, keeping lunch cold with out floating in water. Best investment I made
The postage was prompt and communication was excellent. The order arrived within a week and the included scoop looks great. The bag did have some moisture in it but it didn't appear that any had leaked . I have frozen them and intent to give them their first use this weekend. I would recommend to family and friends.
Awesome
Easy and convenient. Great product! Never buying ice and wasting money ever again!
Fishes are chilling in a cool tub 🤣
These little goodness of ice are a game changer They are. So easy to use and easy to te freeze As my wife says they are gold
Your Ezee Freeze cubes in a vacuum flask are perfect for keeping my injections cold on a long overseas flight .
At first we were skeptical about these but they do exactly what is advertised! They are so much better than mucking around with ice cube trays and smelly freezer ice. Easy to wash and they keep you drink cold for quite some time without watering down a nice gin! I am just about to order some more
After 24 hours some still frozen and cold.
I wanted to buy this dear friend a present that he would use in his Champagne Ice Buckets and also in this portable Cooler Box. He loved them, I would highly recommend them for gifts and I have a few myself for the same usage.
Been the best thing in esky no more water
Love these! Looking forward to really putting them into action in May up north West WA
Love them! & excited to use these reusable cubes in my mobile charcuterie bar!
good way to test out worked great will get a couple more bags to spreed across bags to fit in bag better
Kept the esky cool all weekend with no mess. Great buy
The best ice blocks ever you can put them in with the fish wash them and they are reusable again
Love them Keeps the old orange whips lovely n cold
Keeps my lunch cold all day long
Easy to use, easy to clean and the re usability of (ice) is just unreal and it's already paid for itself already.
They seem robust and good quality It took a while to freeze down 30 kg but now sorted The plan is to always have 15/20 kg in the freezer on my 45 footer Use it in the fish bin clean it and leave it in the freezer again. No more $30 worth of ice each trip again
Very happy to date as no mess and no condensation or dripping. As a traveller, also no noise from rattles or water slopping around.
More than happy with the product
Helps my freezer keep cold when it is not fully loaded.
GOATED
They seem as advertised. A lot of them have these little knobs on them from production. You can see one is cleanly cut as shown in pictures on the website but others have knobs on them. Some are a bit sharp. Can these be cut off in any way that’s recommended?
I sent many emails advising that the product did not keep drinks cool for anymore than about 2 hours. I was told I had to return the products at my expense! And with almost 12 kilos of product this would have been very expense. I was advised that if the product was found to be faulty then you may look at a refund for the purchase cost and the return of the product. I found this unacceptable. I then checked all of the product individually and found that 1 of the cubes had spit open and leaked. I also found, as you can see from the attached photos that across the 3 bags they were 700 grams short of the advertised weight. I emailed again with this advise and asked that you reconsider the refund of what was now proven to be faulty, not to mention underweight. I received no reply I was excited to try this product but was terribly disappointed not only by the product but even more disappointed with your service

More than happy with them and will even be getting some more
Just the ticket to go in my car 12V peltier element cooler so it does not have to cool down from scratch, and I can reuse it, winner.
Brilliant!!
Great product!
Haven’t used it yet
Perfect for using as ice in my wine (Red & White), without watering it down. I purchase 3 bags - filled my ice container in freezer for drinks & 2½ Bags for chilling the Esky. Went to Torquoise Bay all day yesterday, 35⁰... kept our drinks & food chilled all day and easy emptying & cleaning esky on return home. Another #1 purchase.
We dont use ice anymore! No need to fuss with the ice trays, we have our ALWAYS READY ice cubes. Best idea... whybi didnt have this before now who knows. 5 stars!!
Works perfectly for us, depending on how much you need, personally I like the 1.8kg, as it is more than sufficient.
Ready to go
My kids and I love ice in our drink bottles but someone always forgets to fill the Ice tray. Having Ezee Freeze makes it effortless. The kids don’t make a mess, we have an endless supply of Ice, I just wish I waited for the Black Friday sale 😉 Thanks guys
The Ezee Freeze blocks are a fantastic idea, I have only used them to put in drinks so far & they work a treat 👍 I have an event coming up this coming weekend so I’ll pop them in my insulated bag & see how they go 🍻
Blocks are awesome. Delivery poor. Seemed like the package was opened and the bags on the inside Don’t know if any blocks are missing but I bet there are some in the delivery van
