Really great cup. Some write, it would be overpriced. But if you the whole time on piece converts itself, where the spoon so alone already costs about 2.50 euro, I am with Weigersdorf as 1,50Euro the piece. since I can not have the same material quality as expected at the Avent bottles. Custom you honestly do not even. Is only for storage. To this end, completely satisfactory material quality. I find this product great. And that it may break when frozen, is surely nothing new. Can all things happen which are frozen. Before even hold under warm water and then open. Done. Bin thoroughly satisfied and I would buy again at any time
