After purchasing and returning two other resistance band products because they didn't even come close to the caliber of product I use as a Certified Trainer at the Wellness Center where I work, it was with a little trepidation that I ordered the Black Mountain Set. From the speed with which it was delivered, to the carry bag and most importantly the "industrial" quality of the product, any fear I held was dismissed. This is simply a great product. I've built it into the programs that I use with clients (particularly my "road warriors" who need a small profile exercise equipment set when travelling), You have to see the heavy duty guage of the metal clips and feel the stretch/resiliency of the tubes to appreciate just how good this set is. Don't waste time with the "name brand" or celebrity endorsed products - go with the BMP set.
