Car seat questions

Holly • 22 years old from Alabama. I have been married to my wonderful husband since Sept. 2012. We have a daughter. Our family was completed when our Son was born in November 2015.
So I was browsing through the carseat selections and I came across the Maxi-Cosi Prezi. I have fallen in love with it. Has anyone here used it or heard any positive/negative things gs about it?
