The Graco Travel system was a great purchase for us. I researched many different car seats before we decided on this one. It had a great rating with consumer reports and it was a great price.
Besides the initial installation being a little difficult, in regular use the car seat snaps easily into the base. It only takes a few seconds. The straps inside seem very secure but can sometimes be hard to release from the bottom.
The stroller is a great item and rolls easily. It is a little bulky but it has tons of storage room along with a place for a cup or items on top. The car seat latches into the stroller and it was easy to figure out. The stroller also has sturdy locks on the wheels and is lightweight. It folds up for easy transport as well.
I really love this travel system and it definitely comes in handy often.
