Hi, I had the britax viour 3 - good points, lovely & light to push, decent basket, reclines really easily - anything from bolt upright to practically flat, forward/rear facing. Carrycot is a really good size... they get bored of lying flat, though, before they outgrow it!
Bad points - front wheel has a tendancy to "jam", particulary when going up/down kerbs - I know several people with this pushchair who have same problem - it's a design fault which they may have fixed with the new model. And the seat unit is tiny! Fine if you've got a petite child, but my son isn't particulary large & looks very squashed at just 18 months. The footrest didn't extend either. The seat is a "bucket seat", so the whole thing reclines in one piece when you lay it back... which also means the hood goes back with it... so no sun etc protection when reclined. You can fold the buggy in one piece, but it's very cumbersome & heavy doing it like this. Folds more easily if you take it apart.... but it does take up a lot of boot room. Oh and the frame scratches very very easily!
Overall, I liked it... but would have suited my daughter far better than my son... she was tiny, he was't! We never used it forward facing, only rear facing... and it was lovely having the interaction. I'm now using a Mountain Buggy, but really miss not having my son facing me anymore
HTH - btw, we had it in black but you can always jazz it up with a colourful buggy snuggle or similar.
