How customer reviews and ratings work

Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.

Reviewed in the United Kingdom on 17 June 2019
Used these in a pre cooled cooler box on a 4 day camping trip, along with lots of ice cubes and 2 packs of these the beer and meat remained cool until we left. The tent was like a greenhouse during the day in the sun at 30*c + and this didn't make an impact. Not sure how they would fair if they weren't in such a good cooler box but they're up to the task for my purposes. Would recommend.

2.0 out of 5 starsThey don't last long compared to other boards
Reviewed in the United Kingdom on 8 October 2019
I bought these with the high expectation that Thermos would provide a decent product. Well first thing I did was to place these in the freezer to run a test against another board I had already purchased some time before. It has been noted by others that these boards bulge and indeed my own did, maybe they have been over filled with the liquid ?
In a test you need to understand that the board thickness and the liquid type plays a major role and indeed, as expected, the large board fared poorly against my previous thicker board. However If I had a choice I would just purchase the smaller board by themselves along with gel packs.

I was surprised by how large the 800g freeze board was - think A4, whereas the 400g were more A5. I've only used them a couple of times but they have been very effective. And I used the 800g one straight away.

4.0 out of 5 stars Effective ❄️❄️❄️
Reviewed in the United Kingdom on 4 June 2021
Item Package Quantity: 1Colour Name: BlueVerified Purchase
These are slim freezer blocks that fit comfortably into most cool bags and boxes. As such, they can be inserted between bottles and tupperware boxes to give maximum and even cooling.

I use them in our Thermos 30l cool bag where they fit perfectly.

They take about 3 hours to freeze solid in a domestic freezer. They do swell a bit in the process - but that's normal for blocks of this type.

They are relatively lightweight but seem to be very effective. In a well stocked cool bag, they easily last for 6+ hours - even in a high ambient temperature (but don't leave the cool bag directly in the sun!).

Thus far, we have no complaints ☺️☺️

Two were great, however one decided to bulge in the middle defeating the flat design. It is a case of you might be lucky and not get a faulty one.

5.0 out of 5 stars Best Cold Packs ever.
Reviewed in the United Kingdom on 4 August 2020
Item Package Quantity: 1Colour Name: BlueVerified Purchase
Every year I have been trying different things to keep my picnic items cold in my cooler bag and half way through the day it all fails. Ordered this set of 3 ice packs based on reviews and they did not disappoint. Went last week to the beach with my bottle of wine bottles of water sushi sandwiches in the cooler bag and placed these thin ice packs in the bag. And 6 hours later the items were still cold. Bingo.

Thermos stuff these days seems to be hit or miss based on other reviews. I think people expect too much these days!
So I’m glad these freeze packs paired with our 36 can thermos cooler kept our food and drinks nice and cold last night when we were camping.
Left the house at 5:30
We made some hot dogs with fried onions for dinner around 6-7pm
Woke up in the middle of the night around 3-4am and got a fire going, made some soup, had a cider and had cans of coke through to the morning :)
Any money is worth your food being fresh and drinks being cold!

5.0 out of 5 stars Great for a cool bag - really pleased
Reviewed in the United Kingdom on 19 February 2021
Item Package Quantity: 1Colour Name: BlueVerified Purchase
These are brilliant when coupled with a cool bag or a cool back pack like I have got. I use the big flat one against the main flat area of the back pack and the smaller ones on the bottom and in one of the pockets. If I was to just use the big one it would be more than enough to keep everything cool for a few hours.
The other thing I really like to use these for is when I am working from home in the summer. Wrap them in a small towel and put the big one on the floor so I can put my feet on it and one of the smaller ones between my lower back and the chair. Not what they are used for but a suitable solution until I can afford an air conditioning unit!

5.0 out of 5 stars Perfect. Light, thin and best of all - they work
Reviewed in the United Kingdom on 29 July 2021
Item Package Quantity: 1Colour Name: BlueVerified Purchase
We bought these freeze blocks to keep frozen food frozen for a long trip to our self caring cottage in Scotland - the journey was about 10 hours during the hottest days we can remember for years and we weren't very optimistic about whether this would work in those conditions. We put the big one on the bottom of the freezer bag and the 2 smaller ones at the sides

10 hours later we unpacked the freezer bag - the frozen food was still perfectly frozen, as were the freeze blocks - they had worked perfectly.

The boards are light and thin so they don't add much weight to carrying them and very little space is needed. Excellent - very glad we bought them

1.0 out of 5 stars Does the job, but worried the smaller ones will break shortly
Reviewed in the United Kingdom on 21 June 2022
Item Package Quantity: 1Colour Name: BlueVerified Purchase
Should have listened to the reviews, there is an obvious design flaw in the smaller ones. The circular delves, as seen in the product image, are where the front and back of the item is 'stamped' together which is what gives the item structure. In the smaller ones they have purposely not 'stamped' the centre of the item to prevent obstruction to the small print disclaimer that no one reads. This causes a weakspot where expansion of the fluid is focused when freezing, which on first use causes noticeable stress marks caused by the plastic buldging. Over time I feel like this will cause the casing to break and the fluid to leak out. Item does work as intended though, and is considerably thinner than the cheaper alternatives. Can't fault the larger one though.
