I've got the duellette kidz kargo one think it's the one down from this, I love it, but thr heavier child needs to be in the bottom, or its stupidly heavy. X

If your are petite then it's a nightmare to push I had one for about three days it was so heavy and bulky I sold it and got a second hand Phil and teds loved it then decided I wanted a city jogger instead haha I've had 8 doubles and this was the worst one X

I've seen it around few times. No personal experience though.
