*Themaximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.5 stars. In some cases, they criticise the fact that it can be dangerous to use. On the other hand, the robust and durable material and the sharp teeth are emphasised positively. In our practical test, we were able to confirm that the quality and versatility of use of the grinding discs is well received by customers. Consumer criticism of the risk of injury during use is only justified to a limited extent. There is a hazard warning and helpful application tips in the instructions.

Prices of up to €59.05 are charged on the internet for equivalent products. Very cheap products are available from as little as €16.20 . The wood sanding discs from OBA are therefore currently in the middle price segment with a price of €32.99. For the quality and performance received, the price-performance ratio is very good.
