I think their functionality really depends on the age difference. I wouldn't have it for twins, but my two will be 26m apart. My DS doesn't sleep in the pram, so I don't need his seat to recline. I have a capsule for when dd arrives, and she'll be up top. She'll be able to snooze in the capsule for at least 6m (s&s unity), and by then, DS will probably want to be walking. Of course, if it doesn't suit you, sell it and replace it. They do resell well and hold much more value than striders.
