This car seat is good in terms of safety and functionality. However, its compatibility up to 80lb passenger cause problem on the other hand. Its size, specificity the length of its back, it so long that, when install as rear facing, its top will lay on the back of the front seat, which is not recommended and dangerous. The solution involves moving your front seat forward, which will make the front space smaller. I do need to move forward A LOT to get enough space for it, and I know I will need to bear this uncomfortable for a year until it convert to front facing.
