Hello, I wanted a good helper for my windshield. Because if I wash the glass from the inside, it is always stressful. More for acrobats. The disk cleaner, it is much easier. The handle can be extended. The cleaning disc is mounted on a pivot and thus nicely adaptable. The cleaning cloth is attached with two clips. Is it possible to wash or replace it with another cloth. The original cloth could have slightly better quality, but that's the only thing I can complain about. Otherwise, for the money a great thing. A good helper.
