While the base, shape, and size are very good, the bath seat does not easily attach to the base, it requires effort and luck.

But the most important thing is that practically you cannot bathe the baby because the base, the accessory where you place the baby, is NOT NON-SLIP! The child slips and falls into the water, with a serious risk of drowning.
For now, and until I get another one, I wrap fabric diapers around the base so that the child does not slip. I am also considering applying silicone with a gun to make it non-slip, because the non-slip options available for bathtubs etc. bother the child's back.

I wonder if the person who designed this accessory has ever bathed a child.
