Price of product fit my pocket book at the time. Needed something fast. Worked very well at first but a month or two after purchasing it the wheels began to fall off. At first I could put them back on, but I had to vacuum a certain way so that they wouldn't come off again. Eventually, it was just easier to leave them off. I have only changed the belt twice in a years time. Which isn't bad. I guess you get what you pay for!
