Buckle Bopper vs. Unbuckle Me - has anyone tried both? I need something to help my six year old release herself from her carseat when I can't get to her to help (like in the carpool line). I'm wondering if people who have used these tools thought they worked, and if one is "easier" for a child to use than the other. I read the reviews on TCSL; she didn't have an opinion, really.
