Query: ABSOLUTELY HORRIBLE AND UNSAFE

Still didn't feel good about the carseat even after a fireman installed it. Sure enough, it tipped over with my son and I had to reach to the back seat and pulled it back over, then pull off on the shoulder and check on my screaming son. We have tried it in four cars, two with teather, two without, still slides. Vehicles we have tried--2001 Altima, 2001 Xterra, 2006 Frontier, 2006 Pathfinder. Carseat is way too heavy as is stroller. Stroller does turn on a dime, that and the styling are the only high points. Hard to get things in and out of the storage compartment if the seat is all the way down. Hard to snap the carseat into the stroller, hard to recline back of stroller. All in all, I give this system a big F.
