I like this kit it's easy to use, store away and can be used anywhere. By adding multiple strands together it increases the load. It is a convenient alternative to the gym. It is a different type of resistance to weight training and adds something extra. Using them in conjunction with weights I have found it has really benefitted.. so glad I brought the set and I'm using it regularly . I particularly like the different reisitance strengths so I can work my way to the strongest strength so I can break myself in gently!! very pleased with the product and the quality
