I bought the extended mouse pad for my desk and according to the mentioned size it is bigger. It actually measures approximately 36 x 17 inches. Fits my desk perfectly and is amazing value of money as i bought it during sale. The surface seems durable and does not slip on the table.
Pros: Value for money. Good quality rubberized material. Big enough for most setups.
Cons: Edges are not rounded. Surface is not slippery enough for hard core gaming.
Overall it is a great buy and will definitely recommend this product to anyone looking for a big mouse pad to cover a large part of their setups.
