Purchased this for a gift to be used by my grandson. Its was one of the few seats rated to use the harness up to a 65 pound weight limit, which tilted the decision in the favor of this seat. My son/daughter-in-law are so far very happy with the seat. The only problem my son initially had was with the mounting brackets which he said were somewhat farther apart than their previous car seat's brackets-- he said if he couldn't line them up with the brackets in the car, he would mount the seat using another method. I havn't checked with him to see how he ended up mounting it, so can't report on that. They feel happy with the quality of the seat and that my grandson should be able to use it for quite a while, as he is almost 3, tall for his age, but not very heavy and the harness straps will be able to adust to his shoulder height as he continues to grow. Looked at many seats and very few accomodate the harness use past 40 pounds, and we all feel the harness is the safest.
