I advise everyone who buys to take either smooth hard carpets or expensive high-quality rugs, for example, boona from China, the rug costs from 2-3k, but together this mouse with such a rug is an ideal product. Separately, I tried about 8 surfaces, the cursor just behaved terribly, many may think that the mouse is defective, but it's not, the product is just very sensitive to the coating. Not just this company makes rugs for a small price tag.
