Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*

Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.5 stars. Positive customer reviews particularly praise the streak-free cleaning and the high suction power of the cloths. However, individual cases complain that the product does not clean streak-free. In our practical test, we were able to confirm that the cleaning performance of the cloths is very good. We cannot confirm the streaks left behind.

Prices of up to €25.99 for four pieces are charged on the Internet for equivalent products. Very inexpensive products are available for as little as €12.98 for four pieces. The STARKL microfiber cloths are therefore currently in the lower price segment with a price of € 12.99 for four pieces. For the quality and performance received, the price-performance ratio is very good.
