For us, this bathtub was life-saving. We have the bathtub permanently attached to the frame and the changing table on top. We open the changing table, give the baby a bath, immediately close the changing table, and dress the baby directly while the bathtub drains. The fact that it has wheels has been incredibly convenient for us because we can move it around the house wherever we are, and we haven't had to bend over once for bathing, changing diapers, or changing clothes. Underneath, it has compartments where we can keep all the bath and changing products organized, including diapers, sponges, creams, and brushes. It has a special cup with holes for easy washing and rinsing of the baby, which has its place in the bathtub and is always within reach.
However, it is sturdy, but the brake doesn't hold very tightly when you close the frame and the changing table when it is not on the frame but open on the side (i.e., when not in use). Sometimes it comes off from one side and needs to be reattached. However, this hasn't caused us any problems; we simply put it back in place.
The bathtub is quite large and not suitable for newborn babies, but we were able to use the small bath we already had inside it until our little one grew bigger (about a month) and it no longer fit. After that, our baby was big enough for us to feel comfortable putting her in the bathtub. The rubber of the bathtub is not at all non-slip, but it is difficult to have such a feature in a product like this. I haven't seen a bathtub with enough non-slip rubber, so let's not be too demanding. It comes with water and soap inside.
The extra feature of the product (for fussy babies) is that when the baby is still small and if the house is big enough, you can take walks around the house with the baby on top of it, which calms them down for a while so that you don't have to carry them all the time. Always under supervision, especially when the child starts to turn. However, this saves lives because you can have the child next to you all the time and even have a glass of water, as the saying goes. Some moms with very fussy babies understand what I mean.
If your house is big enough for all the above to be useful to you and you don't have to fold it up permanently, I recommend it 100%.
The only negative point is that it drains slowly.
