my grandson loves the crates and the items he makes are amazing

Eureka Crate

The kits include things that would be hard for me to source on my own. I like the commitment to reduced packaging and waste. The instructions should call more attention to details that people often make mistakes on, because even though they are hilighted a little bit, its too subtle and still easy to miss when working with impatient children.
