The band's came on time and as described.  I have been using the bands 6 days a week for over a month now and did not want to write a review until I had a chance to break the product in.  I am impressed at the overall construction of the bands and there are no visible signs of break down of the material even after continual use.  I would and actually have recommend these bands to anyone looking to purchase resistance bands.  Also, their customer service was outstanding when I called to inquirer about higher resistance bands.  Quality product!
