My younger two use Radian 65 by Sunshine kids, Izaak is forward facing and Hannah is still RF at 15 months old. The techs had never seen the seats before and actually had to look them up on the internet to get a feel for them while they were doing the checkup. Even though Josephine still fits in the Radian and would for another year, the tech was glad to see her in a Booster at her age. She also was happy to see that it fit Jo properly and that Jo could use it correctly.
Me and Zach got kudos for arriving IN our seatbelts as well (its a rarity in these parts for people to wear seatbelts).
They were impressed that Hannah is still rear facing, and then I stated that she is BARELY 23#, the seat is approved to rear face to 35# as of last November even though the book still says 33#, and the AAP recommends RF until 2 years now as long as the child fits within the RF weight and height maximums of the seat. "How do you clean the straps?" You are supposed to clean them??? *snort*...with soap and water and a rag of course. The only change the CPST made was to add some no-slide shelf liner under the seats because they slid on the leather too much after install. *BE AWARE!* Only use after market materials that have been APPROVED for use with your child safety seats and only if installed by a Certified Passenger Safety Tech!!
It was a good experience, and i have been 'recruited' to take the class this fall, which is OK by me...then i can have a cert behind my bossyness LOL!
all the best!
