Sylvania car DVD player with two screens

Black double screen Sylvania DVD player, that attaches to the back of headrests. One movie can play on two screens. The screens have speakers for volume. As is- no returns. Worked for us last we tried it, however, it would stick during some movies if left in heat a long time (we live in FL). But would always work again once cooled off. purchased a vehicle w/ built in DVD player so no longer need or use this. Hasn't been used or tested in 6 months. Again, as is condition. Make offer!
