To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I found the silicone edge a bit of a gimmick; unless my child is looking up when I press the jug against his forehead to rinse his hear, the water still goes in his eyes (obvious, I know). It's cute, my son loves playing with it, but it's really no more effective than using a $5 kitchen jug.
My baby expects the water with fear when in the bath, but with this waterfall rinser it goes all to the back of the head avoiding eyes, so she is loves feel the water go through her body except her face and eyes. Quick delivery and good packaging
