Very disappointed.
Instructions not included, very cumbersome to use and haven’t been able to figure out how to properly use. Very disappointing.

Not as pictured
I am very excited about this item, however the ankle straps are missing the heel strap (that is shown in the photos) therefore the ankle straps dig into the bottom of your calve muscle. Going to let my son try them. But may be returning.

Average bands
These bands are for light use and I would not recommend it to pro athlete over a 150 pounds. From my experience, they tend to slip out after heavy use. For the money you get what you pay for.

Belt doesn’t fit all
The belt was too small and there wasn’t really any resistance while jumping upwards. Equipment was okay it just wasn’t what I expected. I wouldn’t recommend for any males over 200lbs.

Missing essential piece
The ankle pieces did not have the foot strap. So they do not stay in place. Also bunge cord is very weak; minimal resistance.

Not for anyone sizable
This checks only two boxes, which is price and for smaller built people. If you’ve searched around you’ll know that this is definitely on the lower scale of cost and one of the more affordable units out there for this purpose. With that, it’s really not meant for any sizable adults or just in general – more suitable for kids or smaller in nature people. The materials and design is simple and decent enough, but it doesn’t give you the confidence that it’ll hold up for more extensive use – for reference I’m just under six feet and just over two hundred pounds. I let my nephew try it, five and a half feet and one hundred and fifty pounds and he said it felt pretty solid. So if you’re focused on price and it’s not for larger adults then this may do the trick, but a pass for me.
