I use it all the time and can tip it upside down with no leaks so the seal seems good
I didn’t originally get the lid when I bought the haakaa. I used cling wrap for a while which was silly. It’s much easier and environmentally friendly with the lid. I recommend!
I got my first Hakka without the lid and immediately regretted it.... get the lid and stopper if you are picking up the Hakka. Great products as so easy to use and clean etc.
Fits securely and doesn’t leak even when the container is knocked over in fridge! Life saver!!
I didn't get a lid with my first Haakaa, and I regretted it after a couple of spills caused by Mummy-uncoordination. Since I've got my second Haakaa (and extra lid for the first) I haven't had any issues, as the lid has saved my any time my lack of coordination has threatened a spill! Definitely worth the extra few dollars.
