Our pram is the Baby Jogger City Elite and we used our bassinet until DD was 9 weeks. She didn't enjoy it as much as I thought she would and she was SO much happier when we put her in the normal seat in the pram. She had silent reflux though and was a very alert and inquisitive baby so lying down while out and about wasn't for her. We used it a bit though when we went out for in the evening instead of a portacot so it was worth the $$.

I'll be buying a stand for it for our next baby and will use it as our bassinet full time (we borrowed our last one). If I had my time over though, I would have bought the SnS capsule (which also attaches to our pram) and used that instead of a bassinet.
