We have one for DH's car. He never even uses it anymore, because he never drives her in his car. We've used it in the past and it's fine. Not the comfiest thing, but it works as a back up.
I had one and gave it away. We took DS to Charleston in it and I spent half of the car ride holding his head back. In my small SUV, rearfacing, it was way too upright and not comfy at all- his head would just hang there. We ended up with a Britax and it is 1000x better- he is very comfy and his head rests nicely against the side. There are a lot of good deals on older Britax models...we got a Diplomat for $129 from ALbeebaby.com.
