The unit was well packed for delivery. It was enough to unpacking, putting our sportswear and launch us. No editing, no. The elastic bands are made to drive the upper body and I find them very effective. Considering the price I paid, I did not expect such quality. It's been a while since I now have my stepper and we use two. It emits no sound, no grinding. I am very satisfied and I would not hesitate to buy the same product.
