They haven’t used it yet, but the price is great and my kiddos are excited to use it! ### ⭐⭐⭐⭐⭐ Great STEM toy! *by A***R on August 15, 2025* Bought this for my 10 year old grandson and he loves it! It’s very well made and I was impressed at how sturdy the pieces are and the grandson had a blast constructing the various options in designs that were in the kit. ### ⭐⭐⭐⭐ Cross-bow. Surprisingly sturdy and capable. Needs adult to assemble. Much fun. *by L***S on November 4, 2025* Cross-bow. Difficult to assemble. Instructions don't show recognition of elements that are hard to assemble. Perspectives shown in illustrations are not always the ones that would be most informative. That said, the crossbow is exceptionally sturdy and capable. My 6-year-old grandson was delighted.
