Reddit reviews Poweriser Jumping Stilt Classic 158-198 lbs

These exist, they're called Jumping Stilts and they are sold on Amazon.

Something like http://www.amazon.com/dp/B002IAQEDC/

They are a lot of fun, but its really easy to hurt yourself. Practice on the grass as much as you can, make sure theres no rocks around for your to fall on. I'd recommend something like a soccer field.

These fucking things! I'm lucky to be alive...

Not exactly the same, but 1/4th the price

Pretty much the same thing, AFAICT.

Make sure you get the right weight range. If you're too light you won't be able to fully compress the springs for max height. If you're too heavy they'll bottom out which limits height and doesn't feel good.

There used to be a great community for support and tips, but I haven't checked it out in years.

EDIT: Here's the old website. Looks like it's dead now, but the information would still be good if you wanted to read through it. Is funny how these "sports of the future" come and go. Back when I was into it it seemed like it would never stop growing.
