I was very satisfied with our Gracco Quattro travel system. It was easy to use, kept my daughter safe and held up good. Durability I loved using out Gracco Quattro Travel system when my daughter was a baby. From time to time we still use the stroller. It was very durable. We still have the stroller and are saving with anticipation for our next child. Versatility The Gracco Quattro travel system was very durable and was versatile in the needs we had for our daughter, when she was a baby. The stroller also was nice to adjust to putting the carrier in and then when we just wanted her to sit in it. The carrier worked well with carrying her in and out of daycare. Ease of Use The Gracco Quattro travel system was fairly easy to use. My husband was able to pop the stroller up and down easier than I could. So, it may take a little bit of strength to do so. I was able to do it, he could just do it easier and quicker. Safety I was very impressed with the safey of this system, especially of the car seat. We were rear ended when my daughter was six weeks old. She was very safe and protected in this car seat. Ease of Cleaning I did have trouble cleaning baby 'messes' out of the car seat, but I think that would be true for any car seat. Babies just sometimes make messes that are impossible to get out. There were pieces you could remove to wash in the washing machine.
