Bests & Worsts Reviews from Amazon

bought this for the trip. It's good as it's very portable, but 2 main issues for my 7 yo to use. 1. this might be "cogenital". It's too low for the sitting position. My 7 yo sit on that, and she could not see anything outside the window, made the 5 hr trip very boring for her 2. this might be an indeed safety concern. When the child sitting on it changing position, the back piece might move up to the seat back, making the booster seat as "L" shape, by doing so, the seat belt will move up to child's neck position from shoulder. I would suggest to have some kind of clip to keep the bottom 2 pieces flat to prevent it from happening. Overall, it might be a good alternative for a short drive, but certainly not good for a long haul
