I just had my first outing with this stroller and loved it. I have the Safety 1st onBoard Air so it's one that clicks right into the frame. I love the security the *click* gives. I must say my favorite part of this frame stroller was the built in sunshade - it's easy to pull out and hook onto the carseat so baby is shaded and has some privacy! The storage compartment under the seat was also pretty roomy and easier to access than other stroller frame systems where you literally have to remove the carseat to stow or remove anything! It moves very nicely too - easy to maneuver even one-handed.
