TLDR: the product is made of poor quality materials and is poorly designed, and they were not willing to send a replacement I purchased their heavy rope a little over a year ago and only used it moderately without really stressing it much. The rope cracked at both end near the handles, and they refused to replace the product because I was out of warranty by 2-3 months. Instead they gave me tips on how to hold the rope in the future to avoid this. Which is quite frankly ridiculous, given a skipping rope that is used moderately should last years. The rope is made of poor quality materials and the handle design digs into the rope and damages it. I would advise against using this brand of products.
