Based on our own experience these disposable microfiber cloths are not worth the investment. While they may seem like a convenient option for cleaning, they are not as effective as traditional microfiber cloths .The major con is that they leave streaks and residue on surfaces, making it difficult to achieve a truly clean surface. Additionally, the fact that they are disposable goes against our commitment to sustainability in the industrial and scientific fields. Save your money and opt for a reusable, high-quality microfiber cloth instead..
