The lid does not stay closed.  Be very careful how you handle the bottle when full.
I had hoped that this product would have been better.  The opening is for a child.  An adult would get urine all over their hands and floor.  I tried it,  didn't work for me.  I sterilized it and gave it to my mom, who is a tiny person and she said the same.  We used it as instructed.
