Review on EUREKA Brand Style R Vacuum Belt: Ensuring Optimal Cleaning Efficiency with Superior Durability by Nuzhat Shaver

Installed perfectly on my 4870 GZX. Stretching is not necessary. Seems working. Picture from another reviewer complaining about authenticity is the same as what I received. I don't see any real evidence of authenticity or lack thereof, so I'm inclined to believe in authenticity as per the details of the Revain article.
