I got the Le joux one I think it was £130 maybe less was perfect for travel
Babyzen yo-yo’s are like universally approved on most airlines but sooo expensive! We had a second hand cosatto woosh 3 for £50 which was so handy and easy to use! (Got it on Facebook marketplace) I’ve also heard good things about bugaboo ant too!
I’ve bought the kinderkraft apino. Lightweight, sturdy and around £100
