My first rope failed after just over a month and half use. After a VERY annoying process of trying to get a warranty replacement through Amazon which was listed as "the seller" and not having any way to contact Pivotal 5, Inc – I called Lifeline direct and in 5 minutes – a new one was on its way. My suggestion – buy direct through Lifeline. Same price and if you have any issues – they are resolved immediately.
As far as the rope itself – I have been using the Lifeline beaded rope for years and have used much lighter, weighted ropes in clubs or hotel weight rooms. This one was considerably better than any previous version I had used in terms of the bearings and motion of the rope. It was also considerably heavier and I will probably get the heaviest one offered after using it (1.25 lb). My one issue is the size of the handles. They feel "big" and do not conform to the hand well. I slightly narrow diameter and a foam wrap would probably greatly enhance the feel.
It is necessary to let the rope hang for several days prior to using. These weighted ropes have a "memory" and the coil takes several days before it loosens up. Also recommend hanging this over two hooks (instead of one) with handles down to keep the "shape" of the rope.
