I decided to write a review because I compared it with a rug from the famous SS brand. My rug is more than 2 years old, it has been repeatedly brushed with soap and water and has remained almost in its original form. And the second got me in a week and was returned to the store. So, I will try to describe and compare: ASUS ROG GM50 vs SS QcK 63003 (black): good glide - fast glide; large weaving of fabric - fine weaving; qualitatively stitched - not stitched; dense (the rubber lining cushions a little) - not dense (almost like a rag); the dust particles themselves do not look for this rug - all the dust is collected and tightly eaten; easy to clean or vacuum - very difficult to clean even with a vacuum cleaner. There was no difference in cursor positioning accuracy.
