I have a Croozer Kid For 1. It’s great.
Use it most days to ferry my son to his childminder and also for the odd weekend jaunt. It’s well built and very cosy, an important factor as we need to go out in any weather. The reason we went for this one was that it converts to a swivel-wheel buggy very easily (also converts to a fixed-wheel offroad / jogging buggy too). This means I can ride to childminders in the morning and my wife can do the evening pick-up and then walk home.
It is solid though…the steel frame won’t break anytime soon but does weight a fair bit going up the hills. Runs very smoothly though. I lost a plastic part of the hitch at some point but it was easy enough to fix with Sugru.
