Fantastic item.

Am chairbound due to a perforated ulcer. Reliant on Carers who have to prepare my hot 'Ready meals'/Big Soups and come at varying times. Have now purchased a second one for the hot rice/sultana puddings - yum-yum . . . .

Good quality as expected

I received this free from Ocado in return for a review. Ocado’s description says food stays hot for 9 hours or cold for 14 hours… but the glossy sleeve on the outside says it keeps hot for 14 hours and keeps cold for 24 hours. The tiny instruction sheet inside doesn’t specify. It only says not to leave food inside for longer than 24 hours; contents including tomato and dairy may spoil sooner than 24 hrs. Keep the tiny instruction sheet, located inside, if you think you will want to make a claim in the future on the ten year warranty. Some instructions are as expected e.g. handwash only, no carbonated drinks or dry ice, and do not put in any type of oven etc. For maximum thermal efficiency, preheat or prechill prior to use by filling with either hot or cold water, attach lid, let stand for 5 to 10 minutes and empty water. Ocado says the height is 18.3cm, sorry I make it 18.8cm. Sharing in case useful if you’re trying to fit it in a very small space. The smallest inner dimension is 6cm; as other reviewers have stated, this makes it easier to clean. It's the usual Thermos good quality, so I would certainly recommend.

Good size and great for lunches

My daughter is always asking to take hot food for packed lunches so was delighted to receive this to review. Feels nice and compact but big enough and great for school lunches.

good size and does what it says on the tin!!

Good size and holds lots. Not tried on hot food yet but kept our water cool at the beach and didnt spill! My only bug bear is that the lid / cup goes on at a slightly jaunty angle sometimes (wrong) and you have to make sure its properly on

Good for transporting hot food

Im reviewing this product because I got a free sample from Ocado. Not that I have to transport food much further than my kitchen at the moment, I imagine this will be really useful when I'm back to doing the daily commute. Lush colour and great size too. love it

Great for work lunches

I’m reviewing this product because I got a free sample from Ocado. This will be even more useful in the winter months for taking hot soups/pasta for lunch at work. Decent size & looks smart too.
