I have the egg, with carry cot and car seat adapters so a few pints now were 6 months in:
It’s very heavy, so getting it up a flight of stairs would be murder, only if you live in a house. Car boot is alright, I just swing it in.
Great off-road and strong. I actually don’t think I could break it which is super important for longevity.
It’s massive when ‘folded’ as it is in two parts. We have two big boots though and leave it set up inside. BMW 118D and Seat Ateca
Carry cot was great for downstairs naps, saved on a Moses basket, carried him around house in it with handle and never woke up. Also had a few over nights in it fine.
Plastic covers are annoying and baby doesn’t really like them, that maybe preference but it seems they’re for style rather than practicality.
It’s narrow and can fit through those pesky cars parked on the pavement gaps just fine.
I would again if I had the money.
Not if weight and size are a problem though.
