Jump Snap lets you jump rope without rope
The Jump Snap is a jump rope without the rope. So basically it's the most useless invention ever. It's supposed to let people jump rope even if they don't have the coordination or fitness level required to do so, but that completely eliminates the point of jump rope. Anybody can stand around and jump, it's the rope that trains coordination. They might as well be trying to market two sticks and an instruction manual. Which, sadly, most lazy people would probably buy.
