Waited at Amazon on this device a little longer than usual, but this was already specified in the order. Bin have pleasantly surprised by the quality, as it indeed is a device made of plastic (plastic) and I was very disappointed by another fan of Amazon (with triple cooling Systafex USB Laptop Cooler) and brought him only with some tricks for running (see my judgment). Here one has but gives the impression of solidity only by the thickness of the material used. The cooling capacity can be described as very good with extremely quiet running sound and the existing USB port is working properly. The only slight disadvantage compared to the aforementioned device is the fact that no illumination (as a running control) is present as in the Systafex cooler. One can only check acoustically whether the cooler is running (as with most - also very expensive -models). Otherwise, this refrigerator is highly recommended. Although it is twice as expensive as the Systafex device but his money and worth 5 stars.
