Have the Vibe.. LOVE it!
21 months gap bewteen my kids who are both very tall for their age and no probs at all.
Not too worried about the lack of storage.. I got the P&T bags (saddle bags? Can't remember name) and they work well, although I find I have enough room in my nappy bag to store things anyway, adn I don't generally go shopping on my own but that's because of how far we have to travel to go shopping (200km round trip).
Such an easy to use pram, so light, and my mechanic husband is very impressed with the general set up.
Would def recommend to someone who wants a small age gap.
