I'm currently in the market for a new stroller and have been looking at the Cybex Beezy. It seems compact and user-friendly, but I'd love to hear from anyone who has actually used it. How do you find its performance in different environments (city streets, parks, public transport)? Is it as lightwieght and easy to fold as advertised? Also, how does it hold up over time with regular use? Any feedback would be really appreciated!
