Safety 1st car seat...

Erica
Hello! So my husband and I have the Graco 4ever and Milestone car seats in our cars, and I'm looking to get another 3 in 1 car seat for the grandma and grandpa to use so we don't have to keep switching them from car to car, I saw the safety 1st grow and go car seat today after work at Target (I work there in the Starbucks)
Has anyone had that car seat? How did you  like it? Advise?
