This stilts (chinese made skyrunner brand) go for us 250 +_ and the originals can cost as much as us 2500, so overall quality, performance, safety and durability might be different. My biggest concern is about safety and durabikity. Having bought some chinese made excersice machines and a few others american built i can tell that the second ones would be the righr choice if you are considering mastering the use of this devices.
