I tried one. It was an absolute joke. I threw it straight in the trash. It looks like s*it with the zip-tie holding the layers together, and it's like taking the edge of a cardboard box and trying to clean with it. It may have a purpose, but that ain't for self-serve bays.
I did about 10 years ago. Took them off and got rid of them within a month. The cloth is way too short and at that length it is very rigid. Very harsh on cars. It has no ability to spread out and get in the smaller recesses that are on every car - like around rear license plates, the window area around side view mirrors, around roof racks and spoilers. Nothing I’ve seen gets in there as good as boars hair brushes. It also doesn’t hold or spread the foaming soap at all. Useless.
