Victoria ★★★★★

My kids and I built this little guy in about an hour, and the moment it skittered toward my son's foot he actually yelled. It's a clever little build that makes the motion sensor feel like a real payoff.

Alexander M. ★★★★★

The motion sensor is surprisingly sensitive—my spider skitters across the desk whenever my cat walks by, which is endlessly entertaining. Building it took about twenty minutes and the legs click into place with a satisfying snap.

Matthew ★★★★★

Putting this little guy together took my kids and me about an hour, and watching it scuttle toward us when we walked by was way more fun than I expected. The motion sensor is surprisingly responsive, so it feels like a real science experiment and toy in one.
