Headrest Dvd Kit Advice Sought.

[torvil]

I'm about to replace my factory fitted visteon DVD player with a combined universal replacement headrest system.

I have seen these listed

On that well known auction site and wondered if anyone has any reviews or feedback on the finished product and more importantly the three retailers. I'm suspicious as you have to communicate with the sellers via email only.

Any advice would be great.
