I ordered the last piece from amazon - actually I bought two different colors because I couldn't decide, so I decided to sell one not chosen in my country because it is so rare anyway. The backrest of 52 cm is very nice, even though space-wise, it is a small buggy. Even if rather spacious, at least in the backrest height area and overall length of the sleeping surface, I am just not sure if I will put there my bigger toddler with a winter footmuff!
I love how it drives; it pushes super easy. The manipulation, as well as sturdiness, are much better compared to the Bee we had before. And that rubber handle is also very nice. I also am very fond of the click off system, which is smooth and works quickly and just fine. The included rain cover works very well too and fits just as it should. You don't even need to take it off to take the child out of the stroller, it has a big opening in the front.
You don't need any adapters for the Concord carrycots, neither for their car seat. Just click on, and there you go.
Overall, a very practical, handy small model with a lot of stuff packed inside. Shame it is not so widely available.
