Great for safety but not practical

I bought this car seat (and the matching stroller) after reading several reviews and looking at the consumer guide reports. I ended up buying the Peg Perego over the Graco snugride as many of my friends raved over the Perego. The good thing about the Perego is that it has better side impact protection. However, it is so heavy. Also, it doesn't fit well in grocery carts. It looked so unsteady that I would have to either carry my daughter in the Bjorn or in her stroller. I think in retrospect, I would probably go with the Graco car seat. I think it is much more practical.
