Overall a good product price-wise: the quality I would say is good for the brushes (which is the key part anyway), as these work well and have good resistance, whereas I find the remaining components - in particular the key chain and the carabiner to be of quite lower quality - not up to par and give me concerns with respect to their durability. All in all the product serves its purpose and pricing is below market standards, so I would recommend especially for beginners or heavy cleaners.
