A good choice - made after a long time of thinking and weighing our options.
We bought it in 2019, and after long searching, we decided to go for the Oyster 3 in the Pebble colorway. The best thing about it is the seat unit - and mainly the fact that it folds so well with the chassis. You just fold the canopy back and fold it over. All folds in one piece. The handlebar to lift it and load it in the car is also an asset that not many combination prams have.
Bassinet-wise, it seems small-ish on the first sight, but it's spacious and mainly quite deep. My DS was using it until he was 6 months - and the last months were in winter, so with a footmuff.
I can certainly recommend the Oyster 3.
