Very happy with the product. I 've already tried it. It is multi-function, puts low/medium resistance, perfect for abs but also to strengthen the back and pectoral muscles. For its quality I think I won't need to order another one but if it went bad, I would order one exactly the same. I advise to explore the product well because the part that grabs the feet rotates, to hold them more or less firm and shoes or barefoot. I really do. Great and portable to be able to take it to your gym as in pandemic time it is not advisable to use public material.
Just like the description. It came fast.
I am very satisfied with this product, it arrived quickly, the seller answers all concerns
