I bought this stroller after having an older baby jogger and they have updated a few things that make this stroller one that unfortunately I am looking to sell and won't use. The new handlebar is really a pain to hold and push with due to its shape. The stroller is heavy and really inconvenient - Not worth it if you're using it for a single stroller for sure. With the second seat there is not a lot of room for the kids and the stroller is so heavy to maneuver. I recommend the GT Double Side by side double if you are looking for a doula. It just folds so much easier and nicer. I wanted a stroller that could do it all and be used as a single and as a double. And this one is not a great double and not a great single... so it just really missed the mark in both categories. I prefer two strollers and don't recommend this one. The specs are great but in actuality it is really not a great buy when you touch, feel and push it.
If you are looking for a lightweight frame for a single stroller that will be easy for a car seat to clip into - Cyber is my recommendation. It is what I bought after this one. They are much lighter. Have an easier fold and their handlebar and design is all around much more comfortable.
