Cooling capacity I find ok in the price range. But that would be it then, and why only 3 stars. What I did not like was that the lid without a backup was just completely removable. And what did not work the E was operational plug for 12V. I drive an Audi A4 Avant B6 S-line with original 12 V socket in the luggage compartment. After I was unable to close the plug of the cooler to the trunk, I went to my workshop to check if the car or the icebox plug is a defect. We have found no fault. Plug other coolers were easily connect in the trunk. What did the dealer not understood was that the cooler has to join without a problem on the front of Cigarettenanzünder leave. So who has an Audi Avant B6 should look rather for another icebox. Telephone service, return and shipping has usually worked out great Amazon.
