Are these different from the 'powerskips' of a couple of years back?
They look identical. (although slightly cheaper)
Best use I've seen is the australian couple who do really good Kangaroo costumes using them. (they have huge kangaroo testicles that squeak when you squeeze them, kids follow them around squeezing their balls and laughing.)
I've got a pair of Power Risers from superdairyboy a couple of years ago. I am quite satisfied with them and the quality for the price. I have not done anything on them except run and jump about a bit, so they have not been used very much. I also bought two extra springs when I purchased the stilts as backup but have not needed to use them yet.
I used a pair for one gig. I was holding my breath while I was jumping around and wound up making the muscles in my back sore, really sore, for like two months. I think you need to breath as you land and stuff to prevent injury.
I got one of these from them with the hopes of using it in my show....but man it is heavy as F**K!
They just came out with a lighter cheaper one and I want to experiment with that one...also there is a relatively new model from a different co. that uses air pressure...kinda based on the sharper image fold up one...but more extreme...triple chamber and pressure gage for extreme jumping...it supposedly rivals the flybar and seems more compact.
