Absolutely awesome product, these replaced so many single weight dumbells and I have so much more space. I like they are easy-to-use and adjust. I highly recommend this product.
My family has a small space to work out. We are 2 young teenage boys that are just getting into working out my husband and myself. This gives us the ability to each individually train without taking up too much space.
I had never seen them before until I got them as a gift. They do take some getting used to especially while in the midst of working out but they are good space savers that provide a lot of flexibility while exercising.
