After I had some time looking for ice-forms that you do not have to throw away (disposable ice cube bag) and not so annoying around drip during filling u. Transport to the refrigerating compartment, I bought after a long search this form, also due to the good Resensionen here at Amazon. The problem is that the fastening straps break in the cold, you can possibly handle even by warming up the entire form before you remove the ice cubes in the air or under warm water. Then you get the lid down and also heal the ice cubes dissolve well out of the mold. Really I was disappointed, however, that the shape is not very close, despite the promise of Emsa "100% leak-proof" yet. I ask myself already, why not Emsa has better quality control (occurs on both new forms). For 6 euros per form I expect more quality!
