Safety 1st swivel bath ring Reviews

I wanted to review this Safety 1st Swivel bath ring for a couple reasons.  First, I like this product and find it helpful. Second, many people buy these second hand, or get them handed down, and may not have the safety information they should.

This swivel bath ring is a seat for a baby who is able to sit upright and has outgrown the infant tub.  The baby sits in it as it is suctioned to the tub bottom. It can swivel around to reach all sides of baby, and has these decorative bead type things on the front for baby to twirl. The bottom has four suction cups, which will not work on a textured tub...

Unfortunately with my tub it doesn't suction because I have a stupid plastic tub insert thing. BUT if i'm in the bath with baby i can hold it down so the suction doesn't matter. My son is fixated on the colored rings on the front of the seat so he sits still really nice in it. As far as safety goes with this seat, it seems that it would be easy for baby to slip out of it if you weren't holding baby or hovering right over baby. But when we are taking a co-bath...
