Car seat questions.

Tasha

I've watched tons of videos and read so many reviews but now I'm starting to second guess myself. We've looked at the products in stores and I'm having a hard time deciding what's best. I'm very interested in the baby trends flexloc car seat with the expedition jogger stroller (Love the stroller because we travel a lot and it has the bicycle tires that would go over rougher terrain better) but now I'm getting mixed reviews about the car seat not lasting long. Whatever we get we planned to use for more than one child if we could. I've seen some graco travel systems that are similar but don't like them as much. I've also heard the handle is difficult and they don't fit well in several vehicles. I'm not due for a while so we have time to decide. I was just wanting advice from other parents that have used these products before.
