The media could not be loaded. My 11 yr old loves them. He's a short guy so I'm not quite sure these hit him where they are supposed to thigh wise. Left some very gnarly bruises all over the back of his thighs. He looked like a patient that fell while on blood thinners. We couldn't believe he was still running around on them after seeing them. But they work as intended, seem solid. Unfortunately we got them right before winter hit and they have been locked away to prevent him from increasing the likelihood of injury more than what it already is.

Everything is perfect except for the leg hole. Shoes are too big to slip through so I have to remove my shoe to put them on and take them off. Wish all models had the open front with straps and not the closed, padded bar.
Othwise it's a good product.

its an awesome product, works great too. only downside is, the straps are not great, they tend to work themselves loose in time, and you cant pull them tight against the locking mechanism or catch pops out (have to pull straight on the strap itself instead) also, the heel plate would be better if it were taller. on occasion, ill go up, and my heel goes over the heel plate in the back, making for a painful landing. prolly wouldnt be as big of an issue with shoes on though.

so right off the bat these things are quality. extremely durable and high grade. sadly there are a few issues such as the protective rubber on the spring easily scraping off. if someone is looking to buy these, i highly recommend them. asside from cheap straps and cheap pads, they're extremely fun. i could easily run around all day in them. but stamina is very important. these things are no joke if you haven't been active in the past. they're dangerous to your knees as you twist in turn to counter balance and already i can feel mine deteriorate after day one. the knee cushion as well as the straps behind it dig into my skin leaving a slight rash. the time limit is how much pain I'm willing to take. my advice? wear thick padding to prevent rashes like pants or even rags. if you're tall or have long legs, first thing you wanna do is adjust the knee cushion to right bellow your knee (more of a shin guard). to do that you need to loosen the bolts around the bars holding it up. (good luck finding a video of that process. everything is on you when it comes to repair and maintenance). there is a booklet of information including disassembly but again videos are scarce. over all these things are a blast and definitely worth the investment. easy to customize and maintain as long as you have the ability to read lego books

I absolutely live these the only problem is i need straps and can't find a place that sells them so I make my own but don't last too long where can I get replacement parts? So if someone can help me there I'm in USA
