## Questions & Answers

**Q: Can you fill with boiling hot water, and then leave for x hours and add formula at the time you need to feed? Will it cool down once formulas added?**
A: Once boiling water is added the flask will instantly begin to cool, you should immediately add the formula and the flask will cool the feed to the perfect temperature within 2-5 minutes depending on feed size. 

Kind Regards

Team Nuby

**Q: What do I do if the digital lid does not show up red when container has freshly boiled water in?**
A: I'd write or call the manufacturer

**Q: For sterilisation can it go in the nuby uv steriliser? Or how do you keep it clean?**
A: Hi,

The digital lid should be cleaned in warm, soapy water. After cleaning, the lid should be sterilised by UV sterilisation or cold-water sterilisation. You can also sterilise the RapidCool™ digital lid when out and about using hot water from your insulated flask. The RapidCool™ lid must glow Nuby red when attached to the flask to indicate the water is at the correct temperature. Keep the flask upside down to make sure the water is in contact with the lid for at least 30 seconds, then the lid will be safe to use!

For the flask - You can do this via UV sterilisation, cold water sterilisation, steam sterilisation or in a dishwasher. Never steam sterilise in a microwave.

Many thanks,

Nuby UK

**Q: How does it actually work? I read that there is no charger. I understand thr battery lasts life if device for the temp but how doesnit actually cool?**
A: The flasks work like a traditional hot water flask in reverse. No charging or electric is required. There are two different lids for the flasks, one is digital one isn't. You can use the cooling flasks with either lid and just time how long formula remains inside.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfection
*by G***N on 23 June 2022*

Honestly couldn’t recommend these enough!!!My son is very inpatient when it comes to feeding time and trying to cool down a bottle when the water has come straight from the kettle always took a while.We recently purchased these flasks and we have never looked back we wished we had gotten them sooner! They are so easy to use our flask keeps the water hot for most of the night! We will fill the flask at about 10pm and its still boiling hot at the 6am feeding time!Honestly if your looking to make feeds just that little bit easier for you and your little one the I fully recommend!

### ⭐⭐⭐⭐⭐ Excellent, must have baby product!
*by C***R on 24 May 2022*

The Nuby Rapidcool flasks really take the fuss out of making baby bottles and all conforms to NHS guidelines unlike other methods such as the Tommy Tippee perfect prep. It allows you to make bottles up fresh when needed and have them ready for baby to consume in a matter of minutes. Having two flasks allows you to have one on the go whilst one is cooling and being sterilised. I think it will be so handy in the summer when you don't want to make up bottles and leave them (not great for baby anyway). Product also looks nice and streamlined and easy to transport around. Well done Nuby!!

### ⭐⭐⭐⭐ Buy the RapidCool flasks on their own
*by P***  on 28 September 2021*

The RapidCool flasks are very good, they get the job done. However, the regular flasks are awful. They don’t retain heat, at all. So if you want lukewarm water after an hour or two then it’s for you. I prefer to use a regular flask. The only negative of the RapidCool flask it’s that you have to have good lighting in order to see exactly how much water you’re pouring in. The markings inside the flask aren’t very easy to see. The other bits and bobs in the box are nice to have, but can be sourced elsewhere cheaply. Overall, it would’ve just been better value for money to just buy the RapidCool flasks on their own.
