Plus if you dont want to buy cartridges you can always do this
My sister has this and rates it. There was about a million of them in our local Mothercare so we got one for bump. If it doesn't work then it was only a fiver. Not sure how its any worse plastic wise than the nappy bags people usually use?
For years I always avoided these types of nappy bins. I wish I'd started using them sooner.
My one was delivered yesterday and set it up today. Cheap plastic. The 2 halves don’t attach together. Got it for a fiver so can’t complain. Wouldn’t pay full price for this.
These often the top of the lists of 'don't bother buying'
