i got this scart adapter because my tv only has 1 scart socket, and if i wanted to watch a dvd, i had to pull my tv out and swap the freeview scart lead, for the dvd lead....a proper nightmare! anyway this really does the job. i had read a few other reviews about other scart adaptors, and people had said that it didnt work, or the sound and picture quality worsened. but with this it is abseloutly fine! you just plug every appliance you want in, (up to 3 appliances) and switch the buttons when you want to go from one to the other!
