what more do you want? Inexpensive and functional very satisfactory one can actually only awarded the top grade. Unbelievable but true, you hear nothing in operation, although 2 fans are installed. The cooling effect is amazing and the notebook / laptop remains quiet and cool even at peak times. The star deduction is only owed the stability. The lower frame tangled up when the device including lifting the notebook raises concern. I see no danger of breaking, easy and massively does not halt. The small folding webs which are to prevent the PC from slipping, although fulfill its purpose completely, but make a little filigree impression. All in all, the expected purpose is achieved and the product can receive an honest recommendation.
