First satisfactory uses

Product of nice appearance.
No drip, but when the children do fall, it does not spread everywhere (just 3 small holes in the cover cap). No breaks. Apparently these cups are solid nonetheless.
Good grip of my 1 year old son.
I recommend them.
After longer use: when the children have fun shaking the cup full of liquid there is flooding. If your children are machouilleurs / biting as my 3 year old son, beak happen to deform despite the quality of plastic which is however rather rigid and of good quality. I always recommend /
