The brush is doing what it should. Has a lot of dirt and unwanted residents away from our wing beadings (Hobby caravans). After one pass, I wonder how many times I can use this part. I had quite a lot of strength to expend, to pull the brush through the bars - and the wire is bent naturally tidy. I would say that the handle is not positioned correctly. When you hold the brush by the handle, you can not pull hard enough. Certainly the product design is still worthy of revision. Therefore, "not bad" at the end only one vote.
