I bought mine at Target and we do love it!! It makes it really snug and everyone in the van can see it, the downside is Karissa has a buttton fixation and unless we put her in the back with Cameron ( which is what we do now) she turns the TV on and off all the time. I think its a lot safer though it does cut down a bit on your use of the armrest. at least on ours, the TV comes back fruther than i would have expected, also our speaker is in the back so that means right next to my ears. those are the downsides.
On a side note does anyone else find that having the TV/VCR in the car you need to clean the heads more often? I dont know if its just our TV but we have to take a head cleaner with us every time because the videos get really fuzzy.
