Works well. Nice and space saving too.
These are very good, space saving because of their shape, keep things cool, just as intended.

Best Ice Blocks!
If you need to keep things to keep things cool in a larger food bag, these are amazing for picnics or travelling! They are well made. They are slim but effective! The largest board is impressive and works so well! They freeze quickly and stay cold for a good many hours . I was worried that the large one wouldn't fit in my freezer but it's so slim that it slotted in easily! The smaller ones might be a bit big for a kid's lunchbox but for keeping a bigger bag of food cold, they're amazing!

Effective ❄️❄️❄️
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 ☺️☺️

Reliable chill—Thermos freeze boards keep food fresh and drinks cold without leaking or cracking.
Used these in cool bags, lunch boxes, and the boot for food runs—holds the cold for hours. The 800 g block’s ideal for bigger loads, and the 400 g pair slot in nicely around smaller items. Solid casing, no leaks, and they freeze fast. Stack well, clean up easy, and don’t crack under pressure. If you want freeze boards that do the job without gimmicks, this Thermos 3-pack’s a proper bit of kit.

A great purchase for additional cooling bag
We bought these for a cooler bag and they are perfect for keeping fresh groceries cool, especially for protein shakes, energy drinks and yoghurt drinks if you need more fridge space

Good value
These were good value for money for throwing into a cooler bag to take on a picnic. All the picnic days are behind us now, they will be used certainly next year.

Buenos enfriadores.
Buen precio para el lote. Para mi nevera, la placa grande lo es demasiado y no es cómoda de colocar. Pero eso es ‘culpa’ mía...

Soluzione perfetta dal ridotto ingombro per frigo portatili
Soluzione perfetta per ridurre gli ingombri nei frigo portatili. Il prezzo non è elevato e sono facili da sistemare tra le provviste. Forse il formato più grande è un po' ingombrante per alcuni minifrigo, ma in compenso ha una capacità di raffreddamento proporzionata. Considerando un mini frigo da 40 lt in piena estate, immettendo cibi già a temperatura di conservazione, i tre elementi consentono una fruibilità garantita per una mezza giornata almeno.

Pratiques
Tiennent peu de place dans la glacière où ils sont faciles à ranger. Et semblent tenir le froid plus longtemps que ceux que j'avais à poids égal

Thermos Boards seit jahren unser Begleiter.
Da wir die große Thermos Kühltasche nutzen haben wir auch die 800g großen Thermos Kühlpads in Gebrauch, da die perfekt reinpassen. Ich musste jetzt ein Board entsorgen, da es bei der letzten Reise sehr gelitten hat und das war noch nicht mal die Schuld vom dem Produkt als solches. Egal, 6 Jahre hat es gehalten und ich denke das spricht für sich. Ich habe mir natürlich direkt den 3er Pack mit den zusätzlich beiden kleineren Boards als Ersatz besorgt und ich gehe einfach mal von aus, dass die auch wieder ewig halten werden. Die großen nutze ich nur im Urlaub mit der 30l Thermos Kühltasche und hier zu Hause die beiden kleinen bei Einkäufen usw. Die Kühlleistung ist ist immer wieder aufs neue sehr gut.
