Product Name: iWALKFree 3.0 I used this indoors for about two weeks, with a towel between my knees. There are no major noticeable scratches, but I think there are some minor ones. Shipping: The photos show it assembled. I will disassemble it and repack it in the box for shipping. I was able to walk without crutches, and it was very comfortable. I am selling it because my injury has healed and I no longer need it.
