The adapter received was not working. After a technical exchange by email very courteous, they sent me another one that works perfectly. I recommend this company for the seriousness of their customer service and the quality of the product offered for sale. With a Nexus 7 and a Samsung Galaxy S2, I can assure you that the adapter gives me satisfaction on my two products. It must still install two applications: Nexus import media for the Nexus 7 and Galaxy S2 for my Stickmont.
