Review on High-Quality 100mm Polishing Sanding Sponges by Uxcell by Tristan Long

These sponges were a total waste of money. Thanks to my knowledge gained in practice, I can tell you that they are not suitable for industrial and scientific use. The abrasive particles quickly deteriorated after just a few uses, leaving scratches on the surface I was working on. The only pro is that they were cheap, but that was not good enough to make up for their poor performance. Save your money and invest in a better quality product.
