I am not sure what what one can say about pre-measured exercise bands. They are convenient, true to resistance when compared to other bands and latex-free is requirement not a option any more. Yes, when these wear out I will be ordering more as needed.
Perfect for young children to use in P.E. I cut each band in half to make the perfect sized resistance band for preschoolers. Great customer service; not often one receives a handwritten note apologizing for an unavoidable delay with their order!
