What are Lula Clips? They are orange pins, shaped like hands. They attach to the carseat with a safety fin, attached to their back. You pin it on the carseat cover, and put the buckle tongues (the metal pieces that go in the crotch buckle) on the hands. The hands have a strong magnet inside, so ideally the keep the harness out of the way while you put the baby/child in the carseat.
From their site:
Lulaclips™ hold the car seat harness out of the way when loading your child. They are like an extra set of hands when you need it most. Lulaclips™ ensure that you never have to dig the buckles out from under your child and make sure you never risk waking a sleeping baby. They will make you and your baby smile!
I tried it on my daughter's Radian. I wasn't terribly fond of it. I take excellent care of my carseats and their covers. I didn't like putting holes in the cover. And there is a safety feature to the safety pin, so you must use 2 hands to open the pin. I felt like trying to get it off my seat, I was going to rip a huge chunk out of my cover :(
I also tried it on a friend's infant carseat. I had her use it for a week, to see what she thought. I thought it was easier to get on and off the infant seat, perhaps because I could flip the seat around however I wanted (without baby in, obviously). My friend said she didn't like the clips much either :(
I know on the website, they put the clips up near the baby's head. I chose to put them lower because in a crash, I don't want anything extra near my child's head.
