We use this in the tub with our daughter. It has been wonderful!! I like that you don't have to put much water in the tub. Plus if she has an accident in the tub, it is so much easier to rinse out and get clean water as compared to stand alone baby tubs. Plus she loves the openness of the tub and the ability to kick her feet in the water. We wring out the water at the end of each bath and it is good to go the next time. The only thing so far is the temperature indicator fell off about 4-4.5 months into it so I gave it one less star on quality. For the price and functionality, it doesn't get any better!
The quarter size blue disc that is a temp gauge falls off. I found it stuck to the roof of my babies mouth after bath! This could have killed her!! Please do not buy this!! I bought this in a Target store September 2012.
