I tested this car seat as a part of the Stellar Product testing panel. I installed the car seat according to the requirements and got all green indicators. However when I put the car seat in the base, the baby was almost completely upright and after a short period in the car, I found her head slumped forward on her chest. This happened a second time on the short drive home and I uninstalled the car seat and did not use it again. I described the incident in my review. When I read other reviews, several other people reported the same issue. My baby is too young to have head control and this car seat is inappropriately reclined for an infant seat. The older models of this seat are clearly much more appropriately reclined. These need to be investigated before someoneas baby is hurt or suffocates. The seat is Evenflo LITEMAX NXT with sensory soothe and sensor safe.
