I just bought this item to detail my car. After washing them in preparation for their first use, I noticed one of them is already fraying a bit. I am not sure if this was a manufacturer's defect or caused by being put in the wash, but I am not very confident about how durable these will be.
Update: After using them once and washing them again, I noticed a seam on one of the towels is separating from the towel itself. I am returning these and removing another star.
