The clips are a pain in the butt. They make the stroller(s) too wide to go through a standard doorway. So you have to keep unclipping them to go through doorways one stroller at a time, which totally defeats the purpose. Maclaren makes a really sturdy, lightweight umbrella stroller for twins that is awesome. It is so worth the money, especially considering how much longer twins end up using a stroller. Each seat will accomodate up to 55 pounds! My 7 year old still rides in it when one of the twins wants to get out and walk. The best part is that it fits through any standard doorway.
