Rope is so 2005. And the JumpSnap agrees. It's a jump rope system that doesn't use rope. Instead, it appears (little info on their site) that weighted ball spin on handles to make it feel like there is a rope, even though there isn't. We expected some complex motion-sensing, laser guidance system. Apparently such technologies are still triumphed by good old weighted balls.
The idea isn't necessarily bad - especially if you live in a home where you don't want to scuff the floors/ceiling/cat. But at $60, the JumpSnap is about $55 too expensive.
