I had to put a poo nappy in my normal bin once and I could smell it within half an hour. I can never smell it from my Tommee Tippee bin. I buy cheaper knock off refills (you have to keep the grey bit from the proper TT refills) and they work great. I think it's the twist bit that contains the bin as I can never smell the perfume from the bags other than when I put a fresh bag.
I have a TT bin and it’s great, I don’t have any smells from it x
I have the Tommy tippy nappy bin and it’s fantastic! No smells at all x
How often do you empty yours? Silly question x
I empty mine 2xs a week x
Same as Claire
I wasn’t bothered about having one but it does prevent the smells in my experience, even my dog isn’t bothered by it.
