I don't know why these are considered economy, because they fit and work perfectly. I don't know if they are the same as the originals because my originals were pretty crappy, so I can't compare them. I am pleased with this product.

My original weather strip on both windows were in bad shape. These were a perfect fit on my Qtr windows. A little tight to remove because of the age and condition, but installation was easy with a spot of grease to help it slid into the channel. I liked the fact that each piece of rubber was marked as LH & RH.
