Has anyone ever heard of this or have one? Looks like it's basically a flexible tube that you attach to your a/c vent in the front of the car and then run it back to the backseat so the rearfacing child can get A/C.

DS is due in August. We live in south Florida and I am getting really worried about how HOT it is in our cars and how uncomfortable he is going to be rear-facing. I drive a Civic and I don't have any air vents in my backseat, so he's going to be getting pretty much no AC. At 33 weeks pregnant I'm miserable, so I can't imagine putting a tiny baby in that weather. And it's a year-round problem here (although certainly worse this time of year).

I know at home I can run the a/c in the car for a while, then put him in, but it's going to still be brutal if we have to get in the car after it's been sitting in a hot parking lot (like after leaving the doctor's or something).

I have been googling about the Noggle and it sounds pretty good. Car Seats for the Littles seems to be okay with it as a minimal risk (that was my primary concern - not safe as a possible projectile in a crash).

Does anyone have any experience with this thing? It seems a little pricey for what it is ($50) but I'm thinking about buying them for my car and DH's car.
