StaceyL (777.5 days ago) I have the single and the double BOB. There are pros and cons to the double BOB. I love the way it steers, takes bumps in the sidewalk, etc. It `drives` beautifully just like the single. However it`s big. It`s a tight squeeze through certain doorways and isn`t fun to lug in your car. If you take a lot of neighborhood walks (or run) it is well worth it. However we have to have a second double to toss in the car or when we go places that the size is an issue. I`ve tried the Maclaren Twin Techno which okay but not worth the retail price. I bought one used on Craigslist. We`re going to get rid of our Maclaren and use our Joovy instead for those instances. I scored a Joovy for $100 off of babyuniverse.com which was a great deal. In summary: I love the double BOB but a smaller back-up is necessary.
