One job it has to do and it doesn't do it right, the dust doesn't stick on, it spreads everywhere in the car. And after the first shake with the hand, it broke apart.

Hard and doesn't fit everywhere, especially between the teeth and the rim. There are others that you can bend. Other than that, it cleans and does its job.

It depends on the job you want it for. For removing dust and dirt from the car, it works great. If the car has been waxed, it cleans faster and easier. However, if the car is wet and the dust has turned into mud and dried, it's logical that it won't clean well. Neither after an off-road route with a lot of dirt on the body. The telescopic handle is quite convenient and the fact that the head can be removed for washing is also helpful.
