Prep machine vs rapid cool

I had both for my first baby and they honestly have such different roles. Rapid cool was brill for when out and about, prep machine was a life saver in the house. If you only have the budget for one or the other I would personally go prep machine. The rapid cool you have to clean after every use, before using again and when you've got a baby feeding 3 hourly through the night that's just not do-able.
I also ended up stopping using my rapid cool because I found it genuinely easier to take a flask of boiling water and a flask of cool boiled water. Then if I was making say a 6oz bottle I'd do 2oz boiling, put formula in and shake it then add the cool to cool it down (minimicking how a prep machine works). You then also only have to wash the bottle and not the fiddly rapid cool flask.
The lid to my rapid cool broke and I was going to replace for this baby then decided against it and have got rid of it. Xxxx

RapidCool has the advantage that you can use it ensuring the water is properly boiled. Unfortunately, the NHS do not consider bottle prep machines safe as tests have shown that they don't warm to the temperature required to kill germs: https://www.bhrhospitals.nhs.uk/bottle-feeding-/#:~:text=The%20NHS%20do%20not%20recommend,A%20guide%20to%20bottle%20feeding.

I’ve bought both (actually both second hand as well!) as I feel exactly the same. I haven’t really brought anything for breastfeeding as I’m not 100% keen and struggle with mental health so just don’t want the extra pressure. Agree with comments above, I think they both work but we’re going to see what works for us when baby is here/what we find easiest xx

Also you don’t have to clean the rapid cool if you use the hot shot method. Not sure if you’re on TikTok but there’s lots of videos/advice on prepping formula x
