Functional, but STINKY!!
This tub does the trick, though I think the price is a little steep for a simple plastic blow up tub.  It fits great in the tub and fits my 7 month old son with plenty of room for toys and growing.  I was worried it would take up half the tub when suction-cupped to the back wall for storage, but it's not a problem at all and nice to have it close at hand. My one complaint is that the plastic really stinks as it de-gasses. Our tub lived outside for a week or so before it lost the plastic smell.
