My wife and I bought this seat for our son at 4 months old because he outgrew his infant carrier. The reasons we bought it were that it looked easy to adjust, and its relatively compact size. What we didn't know until much later was that the shoulder straps are set too wide for an infant. When our son fell asleep, his shoulders would slide out of the straps-no matter how well it was adjusted. We kept it because we thought it would be better when he was older and forward facing, as he would be bigger and this wouldn't happen. Well, when he did get bigger, we found that the adjustment mechanism is almost impossible to work with the child in the seat. I give up. My reccomendation is to stay away from evenflo. The others are much better.
