I bought Orbit Baby car seat year ago n we just love it. It has all characters what we want like safety, comfortable and durable. I love it because of its base that allows the seat to rotate and makes it easier for me to put my toddler in. However, without the base, it's just a piece of very expensive toddler car seat. The harness is very hard to pull most of the time. I own this car seat for over a year now and I still couldn't figure it out how to fasten it smoothly, and most cases took me longer that I care to spend on strapping my toddler in his seat. The idea is great with the stroller, but, this seat is very heavy, my baby is about 30 lbs, add the weight of the seat, it is IMPOSSIBLE for me move the seat to the stroller. My husband is much bigger and fitter than me but he broke a sweat trying. He could, but not as easy as pictured in our heads when we bought the stroller, so we had to return it. Because of the inconvenience I am really torn in rating this product. For its rotating awesomeness, it deserves a 10, but, minus the inconvenience and heaviness. I give it a 4 because it's definitely better than most seats out there. It could be a 5. I would give it a 5 if it doesn't make me rearrange the harness each time.
