Does anyone have any experience with the Cosco Summit High back booster? We currently have a Britax RA which we love but it's almost time to move to a booster. I know that Consumer Reports gives the Cosco great ratings, however, we originally purchased a Cosco Eddie Bauer 3 in 1 seat and I hated it and felt like the quality was greatly inferior to Britax, so I am skeptical of the booster seats. I am leaning towards the Compass booster but can't find any safety ratings on it, and since it's new, I can find very few consumer reviews. Is anyone familiar with either seat?
