This should be called the tank of strollers. Not because of its size or weight (because it's relatively small and light), but because we've lugged this piece of baby equipment to 4 countries, 10 states, dozens of trips in the NYC subway system and through a particularly brutal snow storm, and it has performed and survived. This thing can take a beating yet still function beautifully. Our baby loves it too.
Priced in the mid 200s (400s if you get the entire travel system that we have), this stroller has many add-ons that make it even more functional. We purchased the cup holder accessory and the car seat insert (so 400 bucks total).
In my humble opinion, this is the best stroller for travel. Since it's not one of those thousand dollar prams, you don't worry too much when you see a bag handler man-handle it. I also think it looks better with the many dings and scuffs that come with international travel. It easily folds up, making it easy to put through security and into the back of Ubers and taxis.
The website states, "The 3-wheel configuration with swivel front wheels provides an ultra-small turning radius so you easily glide through crowds, thin aisles and other tight spaces. Combine the maneuverable B-Agile 3 with any Britax infant car seat and you get the perfect travel system from the 1 brand in safety technology. The Click & Go System allows for a quick and secure connection - no adapters needed."
I'd agree with that claim. Car seat is super easy; however, the wheels will need to be oiled from time to time otherwise you lose that ultra-small turning radius and the wheels become wonky. As long as you keep the oil flowing, the stroller moves like a dream.
