My Roomba (Hazel) is worn to the bone. I didn't need the whole wheel assembly so I ordered these tracks - just in a light shade of green. There were no instructions, but a quick hop to You Tube resulted in an instructional video that had exactly the information I needed. Once I learned to take off the old chains and put on the new ones, she did her job again! They fit just like the originals; Just make sure they are centered in the grooves of the wheels so they are snug. I would buy them again and recommend them.
