This car seat definitely has some drawbacks, but overall, it's worth the effort.  I used two of these seats for about 4 years, and I wouldn't have traded them for anything!

The seat is a little difficult to install, and bulky, but once it's in, you can be confident your child is safe.  The optional heat support, padded bar restraint, shoulder harness and degree of recline are all adjustable, meaning the seat fits your child, instead of trying to fit the child to the seat.  This is important because the seat is meant to be used for toddlers on up, and that's exactly what I did.  I bought them...
