I bought this before taking 14 hour drive with my 4 children and without my husband. We plugged it in and it worked great the first time. The kids were thrilled. Unfortunately every time we used it after this either the second screen didn't work or there was a loud buzzing or the screen was fuzzy. I tried rearranging the cords, changing positions but nothing seemed to help. I ended up returning it and am disappointed that it wasn't more reliable.
