It turned out that it is extremely important to establish exactly the cooler. The pitch was initially on a stubble and thus a bit wobbly. At first ran the cooling, but after removing them from some bottles cooling did not occur. A tent neighbor gave then the tip, align the box exactly and to make stable. The box must be perfectly straight (available in Lot). Then we went immediately continue with the cooling.
Furthermore, the box holds a large extent what the item description promises. Only the ice cubes Preparation is rather seen as a gag. First, it takes forever and then you then ice for two drinks ...
Other reviewers complained about the sealing of the lid, which I agree with. With a bit of sealing tape (eg Tesa P-Profile) I have corrected that. A further advantage by this additional sealing is that the cover strikes less noisy.
In summary, I recommend this box, particularly due to the good price-performance ratio!
My advice: buy in the autumn / winter, because the price is ever at 135, -!
