Nuby insulator flask

I didn’t feel it lasted very long, not to be hot enough for making fresh bottles anyway. I purchased a thermos flask instead as they stay hot enough for around 18 hours

I dont have the nuby flask but i use the thermos flask too and its honestly amazing the following morning its still hot!x

I find my Nuby flask stays hot for a while personally - I always put a fresh boiled kettle in last thing at night and wrap the flask - by 8am it’s still hot enough to make her morning bottle (granted I do go to bed late) but I’ve never had issues with it when out and about and those things xx

thank you! I just need it to last me about 4 hours if that! When you say you wrap the flask what do you wrap it with / in??x

Oh 4 hours I’ve definitely found it’s definitely still boiling! Anything really, a blanket, towel xx

brilliant thank you!! I saw some people online saying it didn’t last more than 2 hours so I was panicking a little but that’s great thank you xx

I recommend thermos flask! but I always “pre heat” the flask just to ensure it stays hotter for longer.
20/30 mins before I leave the house, I add boiling water and let it sit, then just before I leave I empty it out, add a fresh lot of boiling water to take with us! Seems to keep hot above 70 degrees for about 5/6hrs
