Yes, that's an official video from the Super Swim Pro people and, yes, we're pretty sure it features a swimmer dying at the 30-second mark.
Research and Development:
Imagine looking out into your backyard. The neighborhood kids are teasing your dog who runs towards them at full speed only to strangle himself once he runs out of rope. Now, look into your heart and consider whether it would occur to you to similarly hobble your loved ones while they are trying to enjoy themselves in a pool.
If you answered no, you are a better person than whoever invented the Super Swim Pro. Forget the "Super" version, the regular Swim Pro was probably just a rope attached to a collar that fits around the neck. We never thought we would say this, but in this case water wings are a good way to preserve your dignity. Apparently everybody agrees since we couldn't find any reviews online.
