Query: Mistake

I received this travel system as a gift, beacuse it was the one I registered for....BIG MISTAKE!!!! This is the WORST car seat/stroller ever made. The car seat is so hard to strap my 4 month old into, and the stroller weighs about 20 pounds, and takes up all the room in my trunk!!! If my daughter wasn't practically duct taped into the back seat, the car seat would fly all over the car, because the base doesn't hold her secure, it is very wobbly, and is easily tipped over on every turn.
