Hi, I currently am using the Nuby rapid cool for feeds however looking at buying the thermal flasks also so I don’t have to keep using ready mades as they are expensive! How long does the water stay hot for in these flasks and is it still 2 hours that the bottle lasts once the formula is added?
Thankyou

The actual nuby flask doesn’t keep it boiling/hot for that long apparently according to reviews. We have been using a cheap thermal flask from B&m instead with the nuby rapid cool when out and about - think it was a Tower one. And it keeps water hot enough for about 3/4 hours.
Not sure on how long the bottle lasts once made as we make it as and when needed for a feed x

A thermos one is much better to keep water hot

I have the Nuby rapid cool bundle with the thermal flask!
I do not recommend the thermal flask! It doesn’t keep the water hot for long at all. Get a thermos flask!

We use a thermos flask I got on Amazon and it’s great!
