We love it! It's a sturdy and smooth ride, and offers many options and combinations! I also like that you can have 2 seats to it, the basket below is very large and it's quite easy to open and fold. Right now, I am using the frame with the car seat (Image #10). To use the car seat, you need to purchase the retrofitted bar (according the the type of car seat you have, mine is the Graco Snugride 35), which costs about $75.
Because there is no space to put your drink, I just purchased this tray on Amazon.ca ! I can't wait to use it. I'll let you know if it does the trick. After reading reviews, apparently the Baby Jogger specific trays are not strong enough to hold the beverages and are quite expensive (~$50). This Skip Hop Grab & Go Stroller Organizer costs around $25. I love that you can put 2 drinks and that the little iPhone case zips right off!
Now I'm ready for Strollercize!
