Broke down and bought the Stomp Rocket. Thoughts?

My 6yo wouldn't shut up about it at Target so I caved. Tbh it's actually pretty fun? We spent 90 minutes in the backyard yesterday launching foam rockets and he was engaged the whole time. No screen time needed. It's bulky to store but if it keeps him occupied on weekends, worth the $25. Anyone else have recommendations for toys that don't require batteries and actually hold attention?
