This seat is great. I have four kids and need something long lasting that will fit my tall kids, be easy to install, and not take up a ton of space. These fit the bill! I can click them in in under 5 minutes from start to finish (including securing the tether and adjusting straps) they have a long life and convert into a high and low back booster. I have two and if I ever need another seat I will get another of these. They may cost a bit more than some, but the quality, ease and longevity make it worth the extra cost.
