The units were delivered promptly and were well packaged. They are easy to use. The display is good and the volume without the supplied headphones generally sufficient. Our Great is 2 1/2 years and wants but still put no headphones are thrilled and we can enjoy our drive much less stressful. The remote control is working properly and all is well because each assignable Geät is marked A and B respectively. The attachment to the headrest is some getting used to but once you made it a two times it is all within a minute or two. The charging cable is sufficient in my golf combi loose also. So all in all, recommended. I would buy again.
