Ohuhu, Adjustable Jump Rope/Skipping Rope, this is not you elementary school jump rope.  Very well made.  Easy to adjust the length with two small screws.  My son was completely out of breath.  Great exercising tool.  Do not need a partner, which is great being only one son at home right now.  Has a handy bag for storage.  Nice sized handles.  Really enjoyed this product.  Thank you for allowing me to try your product  I recommend this product. Disclosure: I received this product at a discount in exchange for my honest review.
