From the minute we put our son in this car seat I have felt that he is safe. The carseat is heavy duty and strong. It clicks into the base and into the stroller super easy. Even at 8 months old our son still fits in the carseat comfortably with few adjustments. While the carseat is rather heavy, I do feel like it is safe for the baby once he is in it. It becomes a little difficult to carry him around in after awhile, but then we just left it in the car at all times. The stroller is very good quality too. It handles great and is very sturdy. Not one of those blow away in the wind kind of strollers. I love being able to snap the carseat into it while my son is small and the prospect of sitting him up in it for many years to come. All of the cupr holders and compartments are great too. Another great feature is how easy it all is to clean. My son had reflux and spit up all over his carseat many times and I just had to wipe it clean with a damp cloth.
