I got given one of these second hand & have found it very useful. My baby is 10 months old & has been using it in the bath since about 6 months old. She sits very well in the seat & while I would never leave her unattended in the bath it gives me piece of mind that she won't fall over & slip under the water.
Sturdy & easy to clean.
A couple of the suction caps on the bottom have pulled away from the base.

Great to allow hands free in bath - hands free in bath = enjoy play rather than just holding on and supporting. Please consider that some very rounded bottom baths - the suction cups didn't hold and remember to clean underneath and suction cups..
