The advantage is that the plastic is not afraid to babies compared to normal ice cube trays, for example where the plastic chemical could. The cubes come out very easily with the silicone material. But for me it is a very expensive product for the short time it serves !! We after a months our son ended all his jars and therefore most in need. I had read a review on another site I think, as an idea to reuse it as "ice cube tray" or "mold" in cupcakes or cakes ... Good idea. BUT THE PRICE REMAINS VERY EXPENSIVE FOR WHAT IS C !!
