So far so good. Unfortunately, our 1-year-old son got after a short period of use in the balls pool quaddelartigen rash on arms and legs, which went back overnight. The next morning it smelled strongly of plastic in the playroom, our 9-year-old daughter complained of a headache in the room -> room ventilated.
After another game in the balls home (with T-shirt and short summer pants) got our son back this conspicuous rash on arms and legs (and only there), so we had to assume that there has been a contact in response to the balls. Comparable reactions he had never and is otherwise not allergic child.
We have this air without eventually sent to us discernible change the exhalation the seller back for another day.

Digression: The CE marking is a marking according to EU law for certain products in connection with the product safety. By affixing the CE marking, the manufacturer confirms that the product conforms to the applicable European directives. CE marking does not allow conclusions as to whether the product has been checked by independent bodies for compliance with the guidelines. After the CE marking a four-digit number attached (in the case of the balls was not the case), this indicates the involvement of a Notified Body in the conformity assessment procedure. The CE marking is not a seal of quality (quality mark).
