*Themaximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.3 stars. In some cases, the fact that it is perceived as short-lived is criticised. On the other hand, the high-quality and functional design as well as the high cleaning power are emphasised positively. In our practical test, we were able to confirm that the quality and practical design of the rim brush is well received by customers. We were unable to confirm consumer criticism of the durability of the brush in our test.

Prices of up to €23.99 are charged on the internet for equivalent products. Very cheap products are available from as little as €4.91 . The rim brush from Chemicalworkz® is therefore currently in the middle price segment with a price of €16.90. For the quality and performance received, the price-performance ratio is very good.
