For all you twin moms or parents who need a double stroller, please reconsider before buying this stroller. Baby Jogger has the worst customer service. I called TWO DIFFERENT CUSTOMER SERVICE REPS before ordering this product and was told all I needed to make it work for two infants were 2 carseat adapters - at a cost of $120 only to have the stroller arrive and found out I needed the second seat kit at the cost of $129!!! These prices all added to the base cost of the stroller (A Whopping $500) and were not disclosed by Baby Jogger. I called customer service (who, by the way, never responded to an e-mail inquiry) and was accused of lying several times by the customer service representative! They refused to sell the mounting brackets with the second seat and only wanted you to buy the kit which I won't need for a long time. This is a total rip off!! I encourage you to purchase the doubleBaby Trend Double Snap N Go Stroller Frame, Blacke snap-n-go much cheaper at $100. This stroller is a total rip off! I will be returning it.
