Bad buy! Plastic breaks during freezing! Scrap !! End! After initial freezing already a crack in the plastic! Capacity is too low. Cools just a filling and then the water (coolant) is thawed again! There were times jugs of gel as a coolant, which have 4 to 5 fillings cooled, but are torn even after repeated use. These are good and nothing should be banned immediately from Amazon, because the product is really a very bad.
