I was disappointed with this water toy. It's adorable, but it doesn't always work. You're supposed to hold it under water, let it fill up and then pull the string, it should float back up to the surface and swim. Half the time it works, the other half, it doesn't.
We got these because our nephews were coming to town and love to play in the pool. Its fun for competitions to have the points on the side. they are also easier for little hands to throw underwater than the larger toypedo. Definltely reccomend!
