I would never use a regent unless backed into a corner with no other option. The years of scary, questionable test results and the awful installation, I hate it. Back when it was the only choice to keep a kiid harnessed past a short, 40 lb convertible, it had a place. These days, with the plethora of 17-18.5 inch top-slotted 50-85 lb limited seat that are easier, with awesome test numbers, are far better choices, in my opinion.
I love the nauti. I especially love the crash test nuumbers and videos of it.
a 7.5 year old needs a good booster. I like the new probooster, it looks really nicee, Ialso like the parkway sg, monterey, vivo, new compass 570, and iof course the regular old turbo. (provided that particular booster gavethe correct fit for your child and vehicle, of course)
