The ice cube tray looks sophisticated - well made of stainless steel with a low content of (visible) plastic. The lid is also thermally insulating and includes full. You get into it about 80 ice cubes, that should be enough for parties with family or friends. To most important property - the cooling holding the ice - I can not give any information: why - see below. * Why then only three stars? My original favorite was the ice trays Alfi with insulating insert. Of which I had but refrained because standing in various reviews that the glass panels, even at low load (in one case the bucket only tipped on its side) breaks. Therefore, I have ordered these iceTub, as I had assumed that on stainless steel and Styrofoam nothing can go wrong. The greater my disappointment: The first time you fill the ice melted within a few hours. The reason: The inner wall of plastic had a tear. Mind you I have that in mind that after emptying and draining areas was repeatedly water in the tank. It was the previously penetrated into the insulation melt water, which ran back again. I sent the product back. I will probably now choose an ice cube tray, which consists entirely of stainless steel (double).
