Olivia ★★★★★

The swivel base is what sold me—my son spent a whole afternoon fine-tuning the angle to see how far the foam balls would fly. It’s sturdy enough to survive some aggressive launching, and the elastic mechanism snaps back smoothly every time.

Jacob ★★★★★

My kids (9 and 11) fought over who got to swivel and aim it first — the elastic tension gives a satisfying *thwip* and the foam balls fly surprisingly straight for such a lightweight launcher. They've been experimenting with low vs. high angles on the patio all afternoon, and I love that it's totall

Julian ★★★★★

Took me about 20 minutes to assemble with my kid, and the foam cannonballs fly surprisingly far when you pull the elastic back fully. The swivel base makes it easy to test different angles, and we've spent an entire afternoon seeing which shots arc or drop.
