I am satisfied with the cloths. Keep clean car windows inside is not easy, streaks and marks are difficult to remove. I was looking for a towel, which is to be applied without any hassle. And the cleaning effect has convinced me - I have used it dry and the cloth was black. And I had let the windscreen only clean the car windows-contractor. But the result was not so good, who had probably forgotten the disks inside - at least it looked like. I will apply these cloths on the windows of the offices. So 5 stars for the towels and the service from Amazon. Very fast delivery, very good service.
