Safe and hygienic enough

The slip in the bottom of the bathtub are required when you have young children or babies. But the problem I have met is a mold which is housed on the underside of carpets that will stick in the bottom of the tub.
These 6 small grippy make cleaning easier below, and therefore does not create a risk to your child.
The red circles indicate if the water is too hot (HOT appear), however this does not replace the thermometer.

Although the form is very convenient, I think 6 round is not enough for a normal sized bathtub, and must take 2 lots. We, we have a small bath and 6 can cover the bottom and the little walk, so it's really ideal.

I recommend this purchase because at the moment I have found nothing better on the market!
