Super easy to use, no fuss. Easy to click on and off of base, not too heavy. Seems Like I may get more than 6 months use, as it seems to accommodate a taller infant. Great review from consumer reports
ConsMy baby turned out to be a little smaller, so it seems the position in the seat is a little uncomfortable for her, but I'm sure all car seats have some what if a comfort issue. But despite her small stature she is still very secure.
