What parents are saying

AI summary of customer 428 reviews

Customers overwhelmingly praise this product for transforming bottle feeding into a fast, stress-free experience. Most highlight how it cools formula to perfect drinking temperature in minutes or even seconds, eliminating long waits and the need to plan feeds ahead. The digital temperature indicator is frequently trusted for reliability. Reviewers consistently emphasize its unmatched convenience for on-the-go use, travel, and nighttime routines, with many saying they couldn't manage without it now. The intuitive design and easy cleaning are also commended. A few note minor concerns, but these represent isolated cases compared to the overwhelming positive consensus.

    It makes formula feeding easy on the go

    by

    [This review was collected as part of a promotion.] Super easy to use and very convenient. Makes formula feeding on the go a breeze. Much prefer using the nuby rapidcool over my previous method as I find the nuby better and more efficient

    Is a must have for all the moms

    by

    [This review was collected as part of a promotion.] I honestly don’t know how I lived without this with my first baby. With my second, the nuby rapidCool has made feeding so much easier, especially when we’re out. I love being able to have the formula ready and at the perfect temperature. I also use it at home to keep warm water ready, and it helps bring it to the right temperature when needed. Such a lifesaver for busy mums... i love itt

    Perfect temp every time

    by

    [This review was collected as part of a promotion.] Super easy to use! Makes the perfect temp bottles anywhere on the go. Picnics, families house, out and about. Love it! Only downside is it is a little bit heavy, especially when you bring both coolers.

    Must have on the baby gift registry

    by

    [This review was collected as part of a promotion.] This was genuinely really cool, it makes moving around with a newborn so much easier. Long gone are the days having to vigorously plan and schedule feeds, along with waiting for the sterilised water to cool before baby can have a bottle. They are slim and not heavy so easy to transport around and so easy to use.

    So handy for bottles on the go!

    by

    [This review was collected as part of a promotion.] This product takes the guess work out of making a perfectly prepped bottled for sleep deprived and exhausted parents. Perfect for on the go and trustworthy. We took ours overseas with us and it was so useful on the plane. It is consistent and reliable. We use ours every single day.

    Super effective

    by

    [This review was collected as part of a promotion.] This is an amazing product that cooled the boiled water so quickly to make my babies feed. It honestly shocked us how effective it was. Though it's slightly heavy and does need a few hours in between uses, its still a great thing to take with you on outings.

    Safety and reliability are a priority, but didn’t meet the mark.

    by

    [This review was collected as part of a promotion.] I really wanted to love this product. However I was unfortunately disappointed. I trialled it for a week and overall found it inconsistent and unreliable. Following the instructions, flipping it upside down so the thermostat could read the waters temperature, to which it turned yellow. In under 2 minutes the LED turned green, indicating that the water was at correct temperature, sadly on multiple occasions the water was boiling hot and not a correct temperature to feed my baby. As a parent this is incredibly concerning, if I had not have checked the temperature, I could have served my Bub scolding formula and not been aware. The 3 hour reset time also makes multiple night feeds difficult when you’re half asleep and cannot recall which rapid cool you last used. Safety and reliability are my top priorities with a product like this and unfortunately didnt meet the mark.

    A game changer.

    by

    [This review was collected as part of a promotion.] An absolutely innovative product. A essential for formula fed bubs on the go. No more asking for hot water at restaurants etc. I found it so quick and easy to use. It works so fast to bring the formula down to the perfect temperature every time. The indicators are clear so easy to read. Easy to clean and maintain. I loved the little portable formula container that fits perfectly in the flask so you don’t have to carry it around in a bag. Highly recommend to a formula feeding mum.

    Such a great baby product!

    by

    [This review was collected as part of a promotion.] Absolutely love this! Made bottle feeding so quick and easy! I loved how easy it was to clean & I could use my UV steriliser on it as well! The temperature of the milk was perfect every time. It comes with two formula dispensers, only downside was that they only fit 150ml of formula powder so not that great if your baby drinks more! I still highly recommend for anyone with a baby!

    Can’t live without our rapid cool

    by

    [This review was collected as part of a promotion.] We love using the nuby rapid cool for them early feeds and cooler days out and about. Hot water ready in flask, transfer to rapid cool bottle and ready for a feed in 2 minutes. Easy to clean and maintain with the high quality material used. Made our lives easier with our little one.

    Insanely fast cooling

    by

    [This review was collected as part of a promotion.] Its standout feature is its speed. By utilising specialised heat- absorbing walls, it drops the temperature of freshly boiled water rapidly, which is lifesaver when you have a screaming, hungry baby.

    Completely unessential gadget

    by

    [This review was collected as part of a promotion.] This does exactly what it claims to do - cools boiling water down to a manageable and safe temperature. But honestly a completely unessential gadget. Excellent sized Thermos, solid, durable design. It was easy to clean (i cooled water down then mixed the formula in the bottle to keep it cleaner for longer). There is absolutely no reason why a baby cant use pre boiled but room temperature/chilled water. It does not need to be some magical temperature. Formula instructions just say it needs to be boiled and cooled to safe temperature - so you dont give a baby boiling water. My issues with it: 1. Its a whole extra thing to carry around. You now have bottles, formula and these thermos (2 - 3 bottles), plus normal nappy bag things 2. Only can be used once every 3 hours. So you really do need to take multiple out with you. My solution: 1. Don't bother with the product. It is just an over priced baby gadget. 2. Boil the kettle, fill a jug and let it cool on the bench or fridge. Fill your bottles to the desired feed size. Then take bottle and formula with you out for the day. This has you taking a bottle, and formula and not a whole kit of gadgets..
