Review on Konex 30-Inch Heavy-Duty Flexible Dryer Vent & Refrigerator Coil Cleaning Brush by Dhoal Olson

First, I think you sent me a used item. The bristles were very worn and frayed. I bought this to clean my cast iron steam radiators so I decided to just keep it to myself. The bristles aren't the strongest, but the shape is enough. They bend enough to get between my radiators. After only one radiator was used for cleaning, it is almost completely worn out. Many of the bristles are now flattened, some are misaligned, and there are now gaps in the bristles. There are better brushes for your money. This one may look like steel, which is why I bought it, but it's not.
